Broadcast a message to multiple channels

[Yogesh-Dubey-Ayesavi]

Feature Request: Add the ability to broadcast messages to multiple channels simultaneously in Supabase. This feature would allow event payloads to include a list of target channels for broadcasting.

// Use the _realtimeClient to send a message to multiple channels simultaneously

// Define the list of target channels
const channels = ["channel1", "channel2"];

// Specify the event type (e.g., "message")
const event = "message";

// Specify the message type (e.g., "broadcast")
const type = "broadcast";

// Create the payload for the broadcasted message
const payload = "This is a message to broadcast into multiple channels";

// Use the  [RealtimeClient] to send the broadcasted message
_realtimeClient.multiChannelSend({
  channels: channels,
  event: event,
  type: type,
  payload: payload
});

Possible Use Cases:

1. Multi-Group Notifications: Broadcast important announcements or updates to multiple user groups or teams in real-time.

2. Dashboard Updates: Simultaneously update multiple dashboard components with relevant data, ensuring all users see the latest information.

3. Cross-Platform Communication: Efficiently share messages across various communication channels, such as web, mobile, and email, in one go.

4. Event Coordination: Coordinate events or activities by sending event-related messages to participants in multiple event-specific channels.

5. Administrative Alerts: Alert administrators or moderators across different departments or areas about system issues or important events.
