Define access level for users

[Saba139810]

I've written a program with Access
I want users to be able to simply modify or add to their information depending on their level of access.
https://mrplanner.ir/product/login-and-access-level/

I saw an example here that attributes the access level to a group of users, but I need to define an access level for each user with a separate username
Please help me and send me a sample if you have a file
Thank you
