TODO's:

• More secure incoming connection
  • Use from slackeventsapi import SlackEventAdapter see: https://github.com/slackapi/python-slack-events-api
  • Include LetsEncrypt for a valid TLS connection.
  • Validate events from Slack
• Use a single command /kenteken and not also /my_car and use an english name, I like: /car simple and short!
• Make the bot Workspace independend: Its now for a single Workspace (Xebia) using one fileshare with a single csv-file
