PROXY manager - expose another instance

Hi,

I have a problem. I have home assistant (192.168.0.3) exposed to SOMETHING. duckdns. org (it is an example) and i want to create owncloud working on 192.168.0.205 to SOMETHING. duckdns. org/owncloud.

So far I have got working hassio on SOMETHING. duckdns. org and owncloud on 192.168.0.205.

Is it possible to add owncloud to SOMETHING. duckdns .org working on /owncloud with Nginx Proxy Manager? If yes can anybody explain how?

Thanks
