Argo Tunnel for multiple ports?

Cloudflare Tunnel for multiple ports?

Can someone enlighten me if i can use an Cloudflare Tunnel to forward multiple ports on s single domain? So that i can access example.de:3501 and example.de:8090 without using separate domain like http.example.de for port 3501 and service.example.de for port 8090. I didn’t understood yet if that should be possible or not.

I think tunnel doesn’t do this and a webserver (e.g. nginx) is needed in between.
