You can add a colleague if you have the Manager role or above and your organisation’s plan includes the External User Access entitlement. To invite a new team member, go to Users & Teams, then click Add team member above the list. In the Invite User panel, enter their email address, choose a Role, optionally adjust their Activity Category Permissions and Location Permissions, then select Invite User. A confirmation message will appear if the invitation is sent successfully.
If you cannot see Users & Teams or access is blocked by an upgrade prompt, your plan does not include inviting external users, or your role is below Manager. In that case, ask someone with the Owner, Admin, or Manager role to add the colleague for you. To check your role, open Organisation Settings and stay on My Organisations where your current role appears in the list.
