Mobile Notifications Package - defer permission request to a later stage

Posting here in case someone else had this issue and knows how to deal with it, since I can't get any reply in the official thread.
There is a Request Authorization on App Launch option in the Project Settings > Mobile Notifications. However even when disabled, it still triggers permission request on app launch. I need to defer the permission request to a later stage. Is there a way to figure out why it's not working as expected or fix it?
Thanks!
