Add a delay for Android notification permission system dialog

[jvsena42]

Do you mean we should deny it now? 🤔
exactly

Ok, got it. So in order for bg payments sheet to appear we need to do "Don't allow" on this system alert. (Verified it is happening indeed) I think I will keep it as is (Allow), because I see the alert re-appering during the test... which is a bit suboptimal and will surely cause flakiness to the tests.

So, we'll just ignore bg payments for andorid.

Good point, currently the system is fully deciding when stop displaying this dialog, but I could add a delay too.

Could use the same delay of background payments dialog

AFAIK the best practices from Android team for these OS permission dialogs are stating that the UI should "introduce the user to the fact that the popup is going to appear", ie. we need an in-app UI screen with 1 primary button and a text (+ optional image) informing the user that the dialog will popup next, and that we recommend to tap "Allow" on it, explaining why.
