I didn't get notified of a Kobo firmware upgrade for my device

I'm pretty sure there was a feature in the past the notified me of firmware updates for my Kobo Libra H2O. I think I even performed the firmware update using Calibre.
I haven't received firmware update in a very long while. I finally performed the November firmware update yesterday OTA. I may have turned the option off, but yesterday I tried looking for the option but couldn't find it. Was it part the Kobo extended driver that's no longer supported?
Also, I couldn't find an option to manually check for firmware update.

I'm using the latest Calibre version (v9.2.1).
