Resource and role management (user-permissions) for each user in the front-end

Hello everyone! :sun_with_face:
For the past few weeks, I’ve been searching for the appropriate solution regarding resource and permission management for each user. When a user logs in to my website, they can see all the resources, just like the administrator. However, I would prefer that each user has their own data source, just like the administrator. Unfortunately, this seems to be working only in the administration panel, and I’m unable to obtain user permissions in the front-end portion.
I hope someone can help me!
Thanks in advance! :pray:
