Setup with caddy

I have recently discovered and grown to love and started to set up my server with it. Now I would like to set up Jitsi on that server.
Is this possible using only caddy? Or can I set up nginx along caddy?

You can install everything by default, see it is working, it will use nginx by default. Then stop nginx and play with caddy and try to make it working again moving the nginx config to caddy
