How to limit access to a view by users

Hi, maybe this is a simple question, but for me, It is taking me a lot of work to understand how to limit the access for the user to a different Table.

I have an App that groups information on many movements of two different clients. and I need to separate these movements so that each one sees their own only.

already generate a slice with the filter:

I also made a table to add registered users, this table I already added to the app


but i try to create a securty filter:

INDEX(Email List[Plant], 2) = “PCP”

but it does not work… Appreciate your help

Thank you, I reread the article carefully :sweat_smile:

IN(LOOKUP(USEREMAIL(), Email List, Email, Plant), LIST(“PCP”,“PCP”))

its works!!!
