Obsidian vault sync is not syncing Calendarium calendars

What I’m trying to do

I want to use Obsidian sync to have my notes available on all my devices, including the events written on the Calendarium addon.

Things I have tried

I have enabled all file types to be properly synced, I restarted the program, enabled and activated the Calendarium addon manually, and see if my calendar appears on my other device, but it is not there.

All the notes are correctly synced, except the calendar along with the events; what am I doing wrong? Where is the calendar data stored? Is it even included in the remote vault or is it stored locally by default?
