        ITurnContext<IInvokeActivity> turnContext, MessagingExtensionAction action, CancellationToken cancellationToken)
    {


        return Task.FromResult(new MessagingExtensionActionResponse
        {

            ComposeExtension = new MessagingExtensionResult
            {

                 Type = "message",                     
                 Text ="<div><pre>Hello</pre></div>"

Currently OnTeamsMessagingExtensionSubmitActionAsync method does not support html response .It has the following options for responding.

• No response - You can choose to use the submit action to trigger a process in an external system, and not provide any feedback to the user. This can be useful for long-running processes, and you may choose to provide feedback in another manner (for example, with a proactive message.
• Another task module - You can respond with an additional task module as part of a multi-step interaction.
• Card response - You can respond with a card that the user can then interact with and/or insert into a message.
• Adaptive Card from bot - Insert an Adaptive Card directly into the conversation.
• Request the user authenticate
• Request the user provide additional configuration
