Have multiple admins for a domain?

**Is there a way to have multiple users be able to change things like the DNS records and other stuff for a domain?**

I made a website for someone a while ago and they wanted to make an email address for their domain but their previous provider didnt allow that so I recommended ovh, and through the process of transferring the domain and the DNS records I had to walk them through the process instead of just being able to do it myself because I couldn't find a way to have multiple admins/technical contacts for a domain, so the actual owner can change things and I can as well.

Is there a way to have multiple contacts for the same role or is that not a thing?
