Android Wear Authorization not Working

Question

I created an app for the Wear operating system.
I used Android Studio 3.1.3
In this app I inserted a button and on the click of this I would like the watch to vibrate.
The problem is that the permissions of the app do not work.
I entered the request for vibration permission in the manifest, but when I start the app on the clock does not require me permissions and if I check the permissions registered for the app tells me that no authorization is required.
where am I wrong?
this is my manifest
