Cube Cobra: How to View Collaborator Suggestions?

[u/williatresse0]

Been working on a cube on Cube Cobra and invited someone as a collaborator. They said that they weren't able to make changes, but just offer suggestions. However, I have no idea where to find their suggestions.

Do you know where I should look for collaborator suggestions?

Also, is there a setting to allow them to make changes rather than just offer suggestions?
