### Steps to reproduce

User1 shares a file or folder with User3, granting limited permissions (e.g., read, update-only).
User3 attempts to share the same item with User2
UI displays all permission options, including those User3 does not actually have. UI should show only existed permission for User3's share (e.g., read, update-only).

### Expected behaviour

The sharing UI should only allow User3 to grant permissions they have been given. Permissions that are not available to User3 should be grayed out in the UI.

### Actual behaviour

All permissions appear selectable in the sharing UI, even if User3 lacks the authority to grant them.
