WHY IT NEEDS A POLICY

Why gdrive_share_file needs a policy

Sharing a file changes its access control list and permissions settings, making it a Write operation that modifies file properties. While reversible (sharing can be revoked), it has high severity because misconfigured sharing could expose sensitive data to unintended recipients or the public.

From the tool's definition Tool description states 'Share a file or folder with a user, group, domain, or anyone.' This modifies access permissions and sharing settings on existing files, which is a reversible modification of file metadata and permissions.
