Removes site members from an assigned badge.
The unassignBadge() function returns a Promise that resolves when the specified members are removed as holders of the specified badge.
The badgeId parameter must be an ID from your site's Members/Badges collection. Typically, you retrieve the ID from the collection using a query or through a dataset.
You can only call this method when authenticated as a Wix app or Wix user identity.
