How to disable ads for a fee?

Question

Android

In general, what are the best practices in this case? What do vendors recommend and how do you do it?
At the moment there is a Xamarin application, screwed ads are shown at the bottom of the window, but they are annoying for some.
Accordingly, it is interesting how to make a monthly subscription for users with disabling ads.

In theory, somewhere in the settings, create a page with the sub-item "Disable ads".
And add a screen with 2 buttons subscribe, unsubscribe.
What else is worth paying attention to?

I have read these answers.

drag on for a long time. It is not economically viable for me to make my own back-end.
