Joining a team is easy. If you do not belong to a team yet you can send a membership request for that certain team.
On your web platform dashboard page
Click on the Teams menu.
On the Teams page, you can see all the teams listed.
Click the team that you have selected.
And click on the Request Membership button.
Once your request is approved you will now be able to see the other members, interact with them like responding to conversations in your locker room.
