Live TV Source Custom Channel m3u File

When creating a custom channel for a live tv source I go to select Source and select File. It then asks for a path where the m3u is located. I cannot seem to enter the correct path. What should be the correct string of text for a path like this:

volume1/docker/channels-dvr/m3u/default.m3u

(Synology DS423+, Running Channels in Docker)

If it's running in a docker container you need to have a docker volume mapped so it can access the directory.
Here's what I used.
/shares/dvr/HDHR-1323AADB-lineup.m3u

If you have /volume1/docker/channels-dvr volume mapped in the container, you need to use a leading / to make it an absolute path.

i.e. /volume1/docker/channels-dvr/m3u/default.m3u

Of course, you'll need to use the container directory path you mapped it to and not the host (Synology) directory path.

Great thank you that worked
