Permission error android.permission.SHUTDOWN, how to solve?

Help me!
Permission error to make me restart the phone by pressing a button inside the app.

How do I add this permission?

Attached error photo.

Is this related to App to turn off cell phone ? Did you use the suggested extension ?

Yes, it is for the mobile shutdown app.
however, the suggested extension doesn’t meet what I’m looking for.
I need a button within the application, which as soon as pressed will turn off the cell phone directly and not open a dialog box and only then turn it off.

Can you help me to turn off the application directly, just by pressing a button inside the application?

I’m trying to do this procedure with the activity starter, but I’m not getting it.

you can do it only on rooted devices, see also
