Add support for Facebook portal devices to join Nextcloud Talk meetings.
I don’t have a portal my self, but other family members do. So process is based on how I would hope it works.
Portal user has nextcloud talk app installed on portal
On invite to a meeting either via email or link, that invite shows a qr code that can be displayed on a phone (or other screen) that the portal camera can read. That code tells the app on the portal how to connect to that nextcloud’s specific meeting.
