Disable Manage Team for Guests
We were hoping to centralize our external contact management/meeting schedules within a specific team of users internally but we found that Guests can, even if they have no enabled permissions, right click on a channel or team and select "Manage Team", which then gives them a full view of everybody added to that team/channel, even if they are other external guests not in the channels that they participate in.
This is problematic as some clients work in competition with each other.
We are trying to use one Team as sharing information to our customer which have their own private channels but we do no like that they see also other invite users under "Manage Team" option in General channel / Team options.
Hope MS add feature to prevent quest users to access this "Manage Team" option.
