Yes, you got it right!
I had deployed Collabora manually while using non AIO. All managed by TrueNAS. Is their official apps.
I’m totally OK by using Collabora through automated installation. The thing I wanted to use Rubik font. I used for a project report while using non AIO. Some format are missing such as “Rubik Black” I uploaded it through Nextcloud’s settings and doesn’t work.
