How can I send an adaptive card to specific channel with bot?

Question

I want to send an adaptive card to specific channel using bot. I used webhook and it was easy to achieve this, but I have to use bot for curtain scenario in stead of webhook.

When handleTeamsMessagingExtensionSubmitAction is invoked by submit action, it returns an error: Unable to extract ConnectorClient from turn context.

my current code is:

 public async handleTeamsMessagingExtensionSubmitAction(
    context: TurnContext,
    action: MessagingExtensionAction
  ): Promise<MessagingExtensionActionResponse> {
    
  ///other code

   const channelId = 123456

    // Construct a conversation reference with the desired channel ID
    const conversationReference = TurnContext.getConversationReference(
      context.activity
    );

    conversationReference.conversation.id = channelId;

    await context.sendActivity(sentCard);

    return {};
  }

I read this and other microsoft teams documentation, but I'm not sure which information I should follow. What I'm trying to do is very simple, just send the adaptive card to specific channel, but I'm confused because it's a lot of information all over the place and it's hard to find information that fits my scenario.

I appreciate any advice.

You can use like this: await turnContext.sendActivity({ attachments: [userCard] });
