What permissions are needed to add or remove groups from a workspace?

To add or remove groups from a workspace, it is essential to have both Edit Security and Add/Delete permissions. The Edit Security permission is necessary because it grants the user the authority to modify the security settings within the workspace, which includes managing group memberships. The Add/Delete permissions specifically empower the user to add or remove entities (in this case, groups) from the workspace.

Having both permissions ensures that the user not only has the ability to access and view the current security settings but also can actively make changes, ensuring proper management of group dynamics within the workspace. Without these specific permissions, a user would lack the necessary rights to perform such actions, potentially leading to security risks or operational difficulties within the workspace management.

The other options do not encompass the full requirement needed for these specific actions, making the combination of Edit Security and Add/Delete permissions the necessary choice.
