as a home cook who is as skilled as he is opinionated, i can tell you that this is misguided. there is no need to seek this out.
but if you must... first of all, what is "chicken salt"? it appears to just be umami-rich seasoned salt. if you really want to experiment with it, just import it. why deny your curiosity by trying to replicate an ultraprocessed treat when you can just import it? pay whatever it costs and just get it to try. how much could that possibly cost you in this globalized economy? why waste keystrokes when you can just spend $50 at most and get some. will that seriously ruin your finances? of course not.
if you don't want to do that for some weird reason, i suggest mixing something like an instant bouillon with salt. for example, you could take maggi brand chicken bouillon (solid cubes or powder packets) and add that to salt.
Reliable sources inform me that fries chips all my cooking will become significantly better if I learn to wield the majesty and power of chicken salt.
i suggest not doing this. if you put it in everything, you'll probably just get sick of it, and worse, your culinary sense can be warped for a long time. people easily develop persistent flavor associations. as an aside, you can also associate flavors with mental or physical health states. for example, it's common to not want anything to do with the liquor that gave you a violent hangover or the dish that gave you food poisoning.
umami is a great tool, but it's shortsighted to abuse it. not every flavor or dish needs to be enhanced with it. it's a cheap trick. you will enjoy your cooking more if only some dishes are umami rich. flavor heterogeneity is great. similarly, resist the urge to over-salt, over-sweeten, or over-acidify everything. try letting other components of the flavors shine.
i suggest instead judiciously using products like instant bouillon
when it actually makes sense. i can recommend this product:
https://www.betterthanbouillon.com/products/roasted-chicken-base-reduced-sodium/also, flavored salts are stupid. salt control is critical. you should use plain, old salt independently from other ingredients to build flavor. that's why i suggested the reduced sodium version of the product above.
never buy flavored salts or seasoning blends that contain salt. do you know why companies try to sell spice blends with salt? salt's heavy and dirt cheap, that's why. further, i strongly feel that you're better off buying individual spices and not bothering with blends at all (i.e. don't even bother with salt-free spice blends).
store your spices away from heat, moisture, and light. never dispense directly from the container over a hot pot or pan – moisture will get in and degrade them. promptly re-cap the containers. never be afraid of throwing out old spices and replacing them with fresh specimens.
what salt should you use? get a 0.5–1kg cardboard cylinder (with metal, fold-out pour spout) of cheap salt from your grocery store. if your palate is refined enough to tell the difference (mine isn't), then experiment with iodized vs non-iodized, with or without flow agents, sea salt vs mined, etc. with practice, it is easy to dispense from the metal pour spout in a controlled manner without over dispesing. shake the package back and forth with your hand (it's in the flick of the wrist) to get even flowrate as you dispense.
here is my everyday salt. the only ingredient is salt. no iodine or flow agents:

for a finishing salt (intended for applications where the salt is NOT to be dissolved), i suggest a cardboard box of maldon flakes:
https://maldonsalt.com/us/our-salt/it is a very attractive salt that also tastes good. it has a good texture and density for most baked goods. i used to use various sel gris, but now this is my favorite.
forget kosher salt. forget dispensing salt by grabbing it with your fingers. foolish.
my final unsolicited cooking tip for this post is to formulate your own recipes and to cook gravimetrically. that's right, weigh your ingredients. take detailed notes every time you cook a dish and follow up with a brief comment after you consume it.
this is how you improve on the next attempt. as your recipe approaches your concept of perfection, make a spreadsheet out of it so that you can easily change the value of one cell to scale the recipe up or down.
