Mounting Local Volume on CasaOS

[hxck]

Installing Dashy as a custom app with the docker compose through CasaOS' import doesn't work at the moment on stable 0.4.3, but I was able to build the image through CLI and import it into CasaOS so I have a working deployment. That said, I'm not sure how to mount a local storage for the config as what I usually do doesn't seem to work. I have:

/DATA/AppData/dashy/conf.yml:/app/public/conf.yml

It looks like this in the CasaOS settings. This is what I see in Dozzle after starting the container. The file exists and I can see it in FileBrowser. With all of that, Dashy still only shows the default Getting Started area.

Any idea what I'm doing wrong? I'm still newish to self-hosting and linux. Thanks in advance.
