Responding to a button interaction received from the gateway to launch activity
After configuring a button to launch an activity (within a message sent by the app's bot), the activity won't launch. Getting a 'This interaction failed' error message. Is specifying the
interaction callback type = 12 not enough? Are there other parameters needed in the response object body (sent to the HTTP API) to launch the activity (i.e. client ID, bot token)?
