Multiple Tunnels, One Cloudflared instance

Probably been asked before, but as a novice to all this. How would I go abouts setting up multiple Tunnels on a single self-hosted Cloudflared instance on Proxmox?

I have Homelab apps all setup in a single tunnel on one domain, however I want to create another Tunnel that is separated from them, but want it all one server/domain.

Thanks

Go to cloudflare dashboard>ZeroTrust>access>tunnels, use the wizard to create a tunnel (aka it gives you the command to run on your server).
Once the tunnel is showing as activated/healthy, you can click on it and expose as many services as you need by adding public hostnames.

Not really what I’m asking here. I’m wanting to install an additional Tunnel in a pre-existing Cloudflared LXC.

It’s one tunnel per host and one tunnel can be used to expose multiple services. There is no point/benefit in multiple tunnels on same host.
However you may find some manual workaround here: Cloudflared Tunnel - multiple services (domains), different accounts for authentication, the same origin/server?
