Kitinerary extraction is working in Nextcloud mail app?

I have an email connected to Nextcloud mail app.

I want to extract travel reservations (planes, hotels, trains, …) and visualize them easy in Nextcloud mail, add them to Calendar, or forward the to the KDE Itinerary Android app.

I have read in several places that Nextcloud mail app has integrated the kitinerary extractor, and it is using it for the x86_64 platforms.
I wonder how can I check if this is working, since I run an instance on x86 platform and the email from airline or does not show any augmented information or offer to add calendar events.

Also, is there any plan to add support of the kitinerary on ARMv8 platform? This would be incredibly useful for many Nextcloud instances running on Pi or similar SBC.

Thanks a bunch.
