Unable to create a tunnel with subpath in the service url

Hello, I would like to use cloudflared with a service that has a subpath, but it seems like the Zero Trust web page does not support this. Is there any solution for this?

What if you put the subpath in the public hostname section, not in the service section?

The services I use have subpath and if I don’t add it within the service URL, it doesn’t work. I use them with nginx proxy manager for now (proxy_pass https:// service:5001/boombox/)
