Feishu Permissions

Manage access permissions on Feishu/Lark documents and drive files.

• Auth: use tenant access token (same pattern as feishu-doc).
• Get permissions: GET /drive/v1/permissions/{token}/members?type={docx|file|folder} — lists current members and their roles.
• Add a member: POST /drive/v1/permissions/{token}/members with {"member_type": "userid", "member_id": "...", "perm": "view|edit|full_access", "type": "docx"}.
• Update a member's role: PUT /drive/v1/permissions/{token}/members/{member_id} with updated perm field.
• Remove a member: DELETE /drive/v1/permissions/{token}/members/{member_id}?type=docx&member_type=userid.
• Transfer ownership: POST /drive/v1/permissions/{token}/transfer_owner with {"member_type": "userid", "member_id": "..."}.
• Get public link settings: GET /drive/v1/permissions/{token}/public?type=docx — shows link share mode.
• Update sharing settings: PATCH /drive/v1/permissions/{token}/public with {"link_share_entity": "tenant_readable|anyone_readable|closed"}.
• Always confirm the resource type (docx, file, folder, wiki) before making permission changes.
