You can invite anyone in your organization from diio settings. The process takes less than a minute.
Go to diio settings → People.
Click "Invite people". A 3-step wizard opens: Emails, Teams and roles, and Send.
In the Emails step, enter the person's email address. If your company has domains configured, the email must belong to one of them, whether or not you use SSO.
In the Teams and roles step, assign the person to their teams as Leader or Executive on each one. Administrator roles aren't assigned from the invitation.
In the Send step, click "Send 1 invitation" (or "Send N invitations", depending on how many people you invite). The person receives an email with the activation link.
If there are no seats available, the Executive option appears disabled. You can assign the person as Leader or manage your seats.
