Slack Buttons don't work


I am trying to talk to my agent on Slack. I have the actions server and a dialogue handler (rasa_core/rasa_nlu) setup in 2 docker containers running on azure. The dialogue handler has a publicly available url which I have placed into interactive components and event subscriptions fields.

Talking to my bot using text works completely fine.

I can see the button requests from slack hit my dialogue handler.

I use the following command to run the actions server: python -m rasa_core_sdk.endpoint --actions actions.main

dialogue handler: python -m rasa_core_sdk.endpoint --actions actions.main

Does anyone have any idea why my buttons don’t work?
