How to properly pass Automounted USB Drive to docker images

[koalacurioso]

Hi, I'm trying CasaOS: I would like to use it with Syncthing sharing files from an USB drive.

I see that my KINGSTON drive is auto mounted in /media/devmon/KINGSTONE
If I pass to docker this path Syncthing can read but not write on it.
Can someone tell me if I need to change something in the automount script?

I also want syncthing to use an external drive but when it is connected it is not visible to syncthing.
