Who can view my team?
Your team will only be visible to users who accept your team invitation. Both Members and Observers will see the team they are part of on the left-hand sidebar. However, team feeds will not be visible to all team members. Team members still need to be subscribed to team feeds for the feeds to be visible to them.
Users added as Members can also create team feeds and invite participants to them. However, they can only invite team members to participate. Only the team admin can invite new members to your team. Team members' new feeds will be visible to the team admin and those that were invited to the feed, and both the team admin and the creator of the feed can manage it.
