1. Connect to FO with a FO user with very limited rights (FO edition, content modifying...), who is not allowed to manage resources
2. Edit a rich-text metadata
3. Click on add a shared image
4. A popup with resource explorer tree appears, with a message saying my rights are insufficient to ass a resource here
5. i select an image, and save. Apparently, I was able to do it

Something is wrong here

Same issue for feature "Add a link towards a shared file"
