This is a Label that places other widgets at the position
where "<widget>" is found inside the label string. The user can also set
a custom placeholder if needed.
To fully work this will need some work on the sdk side, since the
inviter isn't available after dropping a SyncResponse, therefore after a
restart the inviter is forgotten. Also the display name isn't shown
always correclty because the sdk doesn't calculate it correclty.
