Not every automated action should complete without a person checking it. Google now allows administrators to require approval when a flow affects people outside the organisation, such as adding content to an externally shared file or messaging an external group.
That is a sensible default around customer communications, personal information, contractual commitments and anything involving money or access rights. The flow can prepare the next action, but accountability stays with a person before information leaves the organisation.
The approval control is supported on Business Starter, Business Standard and Business Plus, as well as specified Enterprise and Education editions. More advanced data loss prevention controls for Studio and Gemini have a narrower edition list, including specified Frontline, Enterprise, Education and Enterprise Essentials plans. Do not assume every security control arrives with every Workspace subscription.
