Hi, I am Abdelkrim based in Brussels, Belgium. I am running http://www.alt-f1.be
I am building a bot enabling companies to manage the dunning services.
I prefer open-source software that I can deploy on-premise: RASA is the best-fit.
I am struggling today with the deployment of RASA due to UI constraints on Telegram or Slack: to display more than five buttons on a screen makes the bot unusable 
Any Belgian reader? Contact me to overcome my challenges
