Under the Team members tab, you’ll find a search bar at the top of the section you can use to search for or add team members. At far right of the search bar is an Add team members person icon button, which you can click to add new members to your team.
Note: There's a limit of 10,000 team members maximum allowed in one team (of which 200 can be guests). If a team's member count has reached the limit, users won't be able to add more people to the team.
Below the search bar is a list of all existing team members. Team admins will appear at the top of the list with an orange Admin badge beside the user’s name.
When you hover over the name of a team member, a series of icons will appear at far right. Clicking any of these icons will perform an associated action. These actions will depend on the permissions of you or the other user.
