Teams and Sharing
On your dashboard, click on Invite members.
All workspaces are shared with team members by default. They do not need to be explicitly shared with team members. You can invite guests who are not team members to collaborate on a specific workspace.
A team is a group of users that share access to all of their workspaces. When a new workspace is created, it is accessible to all members of the team that the workspace belongs to.
