Trying to host a cross platform game server using ISP that uses CGNAT

I’m trying to host a cross platform game server, but I’m using T-Mobile Home Internet and they use CGNAT. I’ve been told I can use this as a workaround, but how do you access this network if you are on a console instead of PC? I’ve done port forwarding when using other ISPs, but I’ve never been this deep into networking before so the more details I can get the better.
