Secure calendar with create and update time

I tried tuta as a secure calendar but it doesn’t contain create and update time for the events.
Is there any alternative calendar that is secure as tuta and contain audit (or at least created and update time)?

My tests didn’t show any created/edited times for Proton or Nextcloud Calendars, but the web UI of has those details.

Nextcloud calendar contains created and updated as this is the sulotion I am using today.
Is secure is good as tuta and proton calendar?
They are not in the recommended page for calendar (although they are for email)
