Hi @toninguyen ,
If I understand your scenario, it's pretty easy.
Basically, inside the Power Virtual Agents topic, you can create nodes below your question. You can follow the steps below:
1- Create your question like "What do you want?" (Variable: UserInput)
2- Create a node below your question calling an action to your Power Automate passing your UserInput variable
3- Inside your Workflow, you can create inputs to receive parameters from your Power Virtual Agents chatbot and you can create outputs.
4- You can return outputs to your PVA topic (chatbot)
5- You can create a node like "Show a message" and use the workflow output to show to the user
6- You can create a new question with Multiple options like "Do you want to know more?" with options "Yes" or "No".
7- You can create a condition below your question with "Yes" way and "No" way.
8- If your user said "No", you can click on (+) "new node" below you condition, and you will able to see a little ball
9- Drag and drop the little ball at the beginning of your PVA topic.
Did I answer your question?
