My Teams are teams that you are a member of, a leader for, or teams that are related to teams that you are a member of. You can filter the People and Teams tabs on the People page to show a list of your team members and teams.
On the People page, Viewers can only see people who are on their teams. Organization Administrators can choose to require this filter for other permissions, as well.
The default filter on the People tab allows Team Leaders to see people from any teams that they lead.
Click on the pinned filter to update the displayed list of people.
The Teams Tab gives you the option to filter for My Teams or a list of teams based on other criteria.
