Good to know: Inviting teammates is restricted to Admins.
Admins can add new teammates from the Team tab in the Account dashboard by entering a name and email and clicking the Add button. This action will send the user an email with a link to set up their account. If the user doesn't set up their account within 24 hours, an Admin can resend the invite.
Add a teammate in the Account dashboard
After adding the teammate, you will see them above with a status of Pending. After the user sets up their account, the status will change to Active.
