User/Group Permissions

I have an external HHD with the following settings

The home user as the owner

sambashare as the group (which includes jellyfin user and the home user)

Access set to 777

Jellyfin can access and play the files, and edit the metadata just fine.

The issue is when Jellyfin creates an nfo file with 644 access, but the owner is still the home user. Which means that when Jellyfin tries to edit the file, it can’t since the group doesn’t have write access.

Is there a better permissions/access set-up I can use, or edit the access Jellyfin give to nfo files it creates?

Jellyfin Version:
Installs on Ubuntu 20, no docker

Permission log error:
[2020-06-24 09:07:50.167 -04:00] [ERR] Error in metadata saver
