How to install with Caddy?

Hello,
First of all, I'd like to say thanks for your app, it's truly the best I've seen lately🚀.

I saw that you have installation scripts using `nginx` and `traeffik`, but I already have [Caddy ](https://caddyserver.com/) installed and configured, so I would like to use it further.

I tried to install your app and configure the reverse proxy in the same way as all other applications that are running on my server, i.e I receive an external port from the app's container and set up something like this:

```
example.com {
reverse_proxy localhost:8087
}
```

I ran the application but on client got an error: Unknown Error: Failed to Fetch, in the developer console there was
GET ``http://localhost:3000/providers`` net::ERR_CONNECTION_REFUSED

I found a [comment](https://github.com/hcengineering/huly-selfhost/issues/57#issuecomment-2409016925), that says that you need to set the environment variables correctly.
I tried to adapt the nginx configuration [files](https://github.com/hcengineering/huly-selfhost/tree/main/nginx) for caddy using its [directives](https://caddyserver.com/docs/caddyfile/directives#caddyfile-directives) like `rewrite`, `handle_path` and `header`, tried set variables,
but unfortunately I was never able to configure the application,

### THEREFORE

if anyone was able to set up this with reverse proxy Caddy on a host please show how to do it ✍️👀
