Docker - SMB shares

I am running the docker compose version on Win11. I can add a local directory and browse that in the library.
I have assigned, in Win11, a drive letter to a SMB (Samba) share. I can add that as a collection directory, but cannot browse it.

Are SMB shares fully working in the docker version? Any extra step to take?

so docker on windows is a little stranger than what you would expect as it is using wsl2 in the background and this can hide things from you.
in wsl your drives will be mounted on the wsl vm as /mnt/drive_letter/ for example /mnt/c/
but i’m not sure if you can just specify that in your compose file.

The more complex but better approach would be to use a docker volume plugin that creates a named volume for docker that does the samba mounting, it should hopefully be as simple as adding something like the below to create the volume

volumes:
  my-porn-volume:
    driver_opts:
      type: cifs
      o: "username=[username],password=[password]"
      device: "//my-nas/share"
