API calls for groups/private channels does not work for admins

Description:

When trying to get information on a group through the API as an administrator, I always receive the following response:

{
"success": false,
"error": "The required "roomId" or "roomName" param provided does not match any group [error-room-not-found]",
"errorType": "error-room-not-found"
}

This is probably due to the fact that the admin is not a member of the group, but in my opinion the admin should be able to see all channel and not have to join the private channels.

Steps to reproduce:

1. Authenticate as an administrator user.
2. Call any API endpoint for a specific group such as; groups.members, groups.info, groups.history.

Expected behavior:

The API calls should work because the administrator should have access to all channels.
