How can I see the logs of a running flatpak app? (programming.dev)

Usually, I'd run the app from the terminal.

I'm trying to refresh the online calendars in gnome's calendar gnome-calendar or org.gnome.Calendar but nothing happens. It shows a check mark as if it was successful.

edit: I just reinstalled the calendar via software from flathub and cleared the cache. The app is now unresponsive. I can't uninstall it anymore. reboot.

edit2: after a reinstall, calendar still has the outdated information. Even though I deleted everything. Evolution has the latest data which means that sync is working.

I don't know, it would depend on the app, but you can check in /var/log
