How can I make MineOS run behind my Nginx reverse proxy with a subpath ?

[LeVraiRoiDHyrule]

Hi,

I already have an Nginx reverse proxy server, that I use for my personal site, Organizr, Jellyfin, Sonarr, Radarr, Webmin, Transmission....
I would like to add MineOS to those services. But I would like to ask for help to do this, as MineOS doesn't provide any nginx config file (most server apps with webui do).

All my other apps require that I set a subpath in the app' settings. Here, I would like to tell MineOS to have a /mineos subpath. But I didn't find how to do that.

Then, I would be able to set a proxy pass in my Nginx config.

Could someone help me to do that ?
Any answer is welcome, have a great day
