Suggested Actions not visible in Microsoft Teams

Question

I'll send a pro-active message from a bot to Microsoft Teams with 2 suggested actions that the user can take. But in Microsoft Teams the message is shown like this:

Notice that the message shows no suggested messages! At the Bot Framework Emulator, the same message looks like this:

What's wrong in Teams or my code?

Below is my code to authenticate, generate and send the message:

private async Task BotCallback(ITurnContext turnContext, CancellationToken cancellationToken)
{
    string serviceUrl = turnContext.Activity.RelatesTo.ServiceUrl;

    ConnectorClient Connector = new ConnectorClient(
        new Uri(serviceUrl),
        microsoftAppId: "[MicrosoftAppId]",
        microsoftAppPassword: "[MicrosoftAppPassword]"
    );

    AppCredentials.TrustServiceUrl(serviceUrl);
    ChannelAccount from = turnContext.Activity.From;
    IMessageActivity activity = MessageFactory.SuggestedActions(
        new string[] { "First action", "Second action" },
        $"Hi {userName},\r\nYou've missed some lorem ipsum dolor sit amet:\r\n- **consectetur:** Ut porttitor\r\nChoose an action from below to add them."
    );

    await Connector.Conversations.SendToConversationAsync(
        turnContext.Activity.Conversation.Id, 
        activity as Activity, 
        cancellationToken
    );
}

Answer 1

Suggested actions are not supported in Teams. If you want to display buttons, you could use Cards in Teams.
