LinkField readonly

[tungdt-90]

Currently, my project required to put members into different groups with different permissions. One of that group will only be able to see the content of DataObject (Title, Content..etc) when they log in to admin. I managed well with all other fields, except for this LinkField. In my opinion, when an user of this group log in, they can see the link, but they should not see the button (Add, Edit, Remove).

I checked the code, but cannot find a solution for this.
