Depending on your subscription plan available settings vary. To access user-specific settings and information click on your Username located in the navigation header and select settings from the dropdown.
If your account is based on the free pricing plan, you are not able to have or maintain teams. Therefore only Usage information is accessible.
However, if you have a paid plan, you will be able to see the team overview section in addition to the Usage information. So you can maintain the team by removing or adding members.
To add a new team member or user use the invite new user section. Enter the user's email address into the input field and press the + button to invite the new team member.
If you want to remove a team member hover over the user card and click on the Remove.
