Company Directory or Member List of System Users

I was wondering if someone could build us a member app. That will display a list of Nextcloud users and maybe groups or allow us to make custom list and arrange users the way we need. It would be more of a staff directory of the next cloud users. I have done some much research and people want the contacts app to add the users from backend but, it seems like it’s harder then we think which is understandable. I thought let’s just request an app that does what we need aside from the contacts app.
