Hello:

 

Those tables are about the relation of user/role and the channel .
But currently that feature is not fully implemented .
We plan move that feature in date-site chat .

Sorry for this inconvenience .
 

But you could list the lobby by role by programmely .

for example , You could change the data binding code to:

ArrayList list=new ArrayList();
foreach(Chat_Lobby lobby in ChatWebUtility.Api.GetLobbies())
{
    if(lobby.IsHidden)continue;
    if(!lobby.IsEnable)continue;
    
    //write your code to filter the lobby .
    if( ! WhetherThisLobbyShowForCurrentUser( lobby ) ) continue;

    list.Add(lobby);
}

this.DataList_Lobbies.DataSource = list;
this.DataList_Lobbies.DataBind();
 
Regards , Terry .
