The slackbot is not showing as active and not responding. I have used ngrok to set up tunneling from my localhost to allow for the slack bot to be verified. On slack it shows that the request URL has been verified. I have also subscribed to slack events.
I am following, https://medium.com/developer-student-clubs-tiet/how-to-build-your-first-slack-bot-in-2020-with-python-flask-using-the-slack-events-api-4b20ae7b4f86, to get this bot working. Any help would be great. Thanks.
