How do I switch between QnAMaker and Waterfall Dialogs in Python Azure BotFramework SDK?

Question

Dear Community,

Please help with the Azure BotFramework Python SDK flow implementation I have described below.

Step 1 : I need my bot to ask a question initially when members are added i.e

async def on_members_added_activity(
    self, members_added: [ChannelAccount], turn_context: TurnContext
):
    for member in members_added:
        if member.id != turn_context.activity.recipient.id:
            await turn_context.send_activity(
                "Welcome to the Sample Bot! May I help you with something?"
            )

*This is the 'Welcome Prompt' - "Welcome to the Sample Bot! May I help you with something?"

Step 2: If the response from the user for the 'Welcome Prompt' is 'Yes':

• I need to call QnAMaker and let the user ask a question. After QnAMaker should answers the question from the Knowledge Base, I need to prompt the user again and check if the user needs another query answered. (This is the 'More Help Prompt')

Step 2: If the response to the 'More Help Prompt' is 'Yes':

• Repeat Step 2

Step 3: else if the response to the initial 'Welcome Prompt' or the 'More Help Prompt' is 'No':

• I need to run a Waterfall Dialog and prompt the user for getting various inputs in a sequential manner. Ex: Name, Age etc.

I don't mind if the flow isn't exactly as described above. The prompts can be anywhere or structured differently and I just need the QnaMaker and Dialog triggering and switching to work.

Any help in calling QnaMaker from Waterflow Dialog will also be appreciated.

I found these implemented in the C# and JavaScript SDKs but, couldn't get a reference code in Python.

Thanks in advance for the help.

Edit:

Adding links of C# and JS references which may help.

The Bot Framework SDK v4 is delivered as an open source SDK on GitHub, targeting .NET, JavaScript, Python, and Java.
