How do I invite others to my team?
Inviting people to your team is done in the "Team settings & members"-menu found by clicking the team name in the upper right corner of the app, see image below.
In the "Team settings & members"-menu you can toggle between Settings and Members. Admins will also be able to see Subscription (not visible in the screen shot below). To start adding new members, toggle to Members.
From this view you will be able to invite new members to your team, remove members from the team and change team roles. To learn more about each team role, go to the Team roles article.
