I'm working on an App where users can see or edit an image. My question is about user permissions and what to show to the user.
Users can have view only or view and edit permissions.
I have 3 options when a user does not have permission to edit:
- completely hide the edit button
- disable the edit button
- let the user hit the edit button and then show a message 'you don't have permissions to edit, please ask someone to give you edit permissions'
Regarding usability, which of these options is the most correct?
