A bot user was added


Works with

	"type": "bot_added",
	"bot": {
		"id": "B024BE7LH",
		"app_id": "A4H1JB4AZ",
		"name": "hugbot",
		"icons": {
			"image_48": "https:\/\/slack.com\/path\/to\/hugbot_48.png"

The bot_added event is sent to all connections for a workspace when an integration "bot" is added. Clients can use this to update their local list of bots. If the bot belongs to a Slack app, the event will also include an app_id pointing to its parent app.
