Using an internal link to embed a calendar in other apps (Text, Collectives, ...) does not work

[noantiq]

Steps to reproduce

1. Create a calendar
2. Add some events
3. Copy its "Internal link"
4. Paste it into Text or Collectives

Expected behavior

The Calendar widget is shown as a preview.

Actual behavior

No preview is shown and the link doesn't open the calendar.

Calendar app version

5.5.2

Nextcloud version

31.0.8

Additional info

This functionality should have been added in https://github.com/nextcloud/calendar/pull/5891 and is documented as follows:

Calendar Widget You can embed your calendars into supported apps like Talk, Notes, etc… by either sharing the public link to make the embed viewable (read-only) to all users or by using the internal link to make it private.

But it does not work for me when using an internal link.
