//
|
||
// To send the message to a specific channel, set the channel_id field in the JWT to the channel’s ID and set the pubsub_perms.send array to broadcast.
|
||
//
|
||
// To send the message to all channels on which your extension is active, set the channel_id field to all and set the pubsub_perms.send array to global.
