Federated Calendar-Sharing with read/write-permission

[mamo2021]

Is your feature request related to a problem? Please describe.

I would like to share a calendar with a user of another Nextcloud instance.

Describe the solution you'd like

Calendars, like folders and files, should be able to be shared via the federated-share function, so that it is possible to grant users or groups on another Nextcloud instance read or write access to a calendar.

Describe alternatives you've considered

This cannot be implemented with the links for external sharing, as only read-only access is possible.
