How to limit user actions?

Hello friends! I’ve read the forum a lot, but I haven’t found how to restrict actions and tabs in the Home Assistant mobile app.
I installed the app for the child to control the location and I don’t want him to accidentally turn something on or off all or another device.

I logged in as a regular user, but he can manage the house.
Please tell me how to limit the functionality of the application. Thanks for the help.
