[HELP] Cannot make facebook messenger notification platform work


I got up to a point where my app is created, my page is created, both seem to be linked.
Notification platform in HA is properly set-up.

When I try to manually send a notification through Home Assistant, the following error message appear in the log:

[homeassistant.components.facebook.notify] Error 403 : (#230) Requires pages_messaging_phone_number permission to manage the object (Code 230)

I tried searching where to enable this permission but I cannot find where it is. I checked in both the Facebook App and the Facebook Page settings.

Anyone has a clue?

Did you get it working?
I can’t get it to work either :frowning:

No unfortunately. I switched to Telegram instead.
