feature option to choose this app in the "autocomplete" function

[fallsdevil]

I would like the application to have the function of activating it as the main autocomplete suggestion, this is a very useful feature when the keyboard identifies the fields to fill in email and password and suggest the data already saved and also ask if the user wants to save or update any credentials.

Planned, I initially tried to implement in in the autofill-service branch but it needs to be completed
