Currently we have a bot that works on many channels (facebook, skype, teams, etc...) and now are integrating with Slack. The problem is the "imBack" buttons both within the hero card and suggested actions do not show up as interactive, instead they are just plain text.
I have gone thru the documentation, and put https://slack.botframework.com/api/Actions in the "Interactive Components" section as directed, but no joy.
This is using Bot Framework v4 (C# Bot Builder v4.5.1).
Also, i have tried Slack in the web browser and Desktop for Windows 10.
What am i missing to get buttons to show up?
