Description

Restrict invitations to either users with specific administrative roles or no one.

Rationale

Restricting invitations to users with specific administrator roles ensures that only authorized accounts have access to cloud resources. This helps to maintain "Need to Know" permissions and prevents inadvertent access to data.

Impact

With the option of Only users assigned to specific admin roles can invite guest users selected, users with specific admin roles will be in charge of sending invitations to the external users, requiring additional overhead by them to manage user accounts.
