Share an item with the current members of a channel by writing a channel entity-access grant. Call it only after the user agrees to share that item, or when they already asked you to share it. entityType is the stored type: calendar_event for a calendar chip, document, chat, project, database, form, call, thread, or agent_session. entityId is that item’s id. A calendar event can be shared only by someone who holds it on their own calendar, and private or confidential events are refused. Sharing again is safe when a grant already exists.
Entity types a channel grant can cover. Values are the stored entity types. calendar is accepted for a calendar chip, whose stored type is calendar_event.
