Enable Approval dashboard for groups

We have deployed a GalaxyNG instance and now i need to enable collection approval tab for users

Here is the flow -

  1. User uploads a collection to namespace where he has access
  2. Some admin users of that groups can go and approve the collection for that specific namespace

Right now there is no option to enable approval tab based on namespace, if i add any admin role to a group then they can see all approval of collections which doesn’t belongs to their Namespace

I tried to found everywhere but didn’t got any solution
