Provide support for Slack buttons

Provide support for Slack message buttons as per: https://api.slack.com/docs/message-buttons

[guidone]

Inline buttons are already supported

https://github.com/guidone/node-red-contrib-chatbot/wiki/Buttons-node

This is a generic node, means that works for FB, Telegram, etc so the list of button-related features is limited. In what are you interested here (https://api.slack.com/docs/message-buttons) that you cannot find in the generic node?

Perfect thank you. One of my developers had literally found this before you responded, so I will close the ticket and give it a go.
