I want to Update / Delete a sent messages by a bot in a previous step of Waterfall Dialog (WFD).

In step 1, a choice prompt is sent as Hero Card. While receiving the result of the selected value right after the user selected a proper choice, I want to delete the sent card in step 1 of WFD or replace it with a second choice card in a step 2 of WFD. The message is a CHOICE prompt message, followed by another similar message, but of a different content.

I couldn’t find a supporting document or sample for such action. Need help pls? Thanks
