How to sync the grist calendar?

Hello!
We have project tasks Grist database.
Each task its attendee. there way to sync these with the attendees’ calendars (Google or others)?
When the question pertains to syncing all the tasks with my own calendar, it is not problem (using n8n or any other similar services). However, how can I implement this when I need to sync it with multiple calendars of different peoples?
Alternatively, is there a way to access these calendars from standard applications (look, Gmail, etc.)?
