I am facing troubles with the setup. I have application, connected business account to it. I am settiing up webhooks using webhooks widget, passed verification. But I cannot test receiving event like messages, while I receive testing of messaging_seen. I wonder what I've done wrong, my app is running in development mode and I didn't apply for advanced access for any of instagram_basic, pages_manage_metadata or instagram_manage_messages. Thank you in advance!
