## Description

Accept, decline, or tentatively accept a Google Calendar event invitation on behalf of the authenticated user. Use this when you need to RSVP to an event. You can identify the event by its exact `eventId` or by `eventName` (searches upcoming events by title). If both are provided, `eventId` takes precedence. The `calendarId` defaults to `primary` (the user's main calendar). [See the documentation](https://developers.google.com/calendar/api/v3/reference/events/patch)

## Props

| Prop | Type | Required | Description |
|---|---|---|---|
| `calendarId` | `string` | No | Optionally select the calendar, defaults to the primary calendar for the logged-in user Options are loaded from the connected account. |
| `eventId` | `string` | No | The ID of the event to respond to. Use this when you have the exact event ID. If you only have the event title, use eventName instead. |
| `eventName` | `string` | No | The title (summary) of the event to respond to. Used to search for the event when you don't have the event ID. A case-insensitive search is performed and the first matching upcoming event is used. |
| `responseStatus` | `string` | Yes | Your RSVP response to the event invitation. |
| `sendUpdates` | `string` | No | Whether to send notification emails to the organizer and other attendees. Defaults to all (notify everyone). |
