Anyone get Quick Invites to work on Oculus Quest?

I am trying to get the Quick Invites to work on Quest 2.

I have got the invite popup to work and can send invites that way. But with the function GroupPresence.SendInvites(..) (BTW there is no SendDirectInvite function in latest SDK), it removes those users from the pop up invite list, but it doesn't appear to send any invites. No notifications appear for the other user.

Why I'm trying to get this to work, is that I want to send a send an invite from my game running in my Unity Editor as a test user to my headset. So that I can test the invite functionality. Obviously the invite popup is not going to work in the editor.

I have a feeling that notifications only get sent after you upload the app to the oculus developer centre then re-download it which would be annoying.
