MS Graph Der Endpunkt POST Teams / Channel / Message zeigt fehlende Berechtigung

Hallo,

der Endpunkt POST https://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id}/messages

oder PATCH https://graph.microsoft.com/v1.0/teams/{team-id}/channels/{channel-id}/messages/{chatMessage-id}

liefert über msgraph immer eine Fehlermeldung zurück, obwohl alle Berechtigungen entsprechend gesetzt sind.
