Bot is unable to process your request

Question

I have a GChat bot with some custom method, and I am unsure what the right "action response" is supposed to be.

I am using the default action response as seen in documentation: https://developers.google.com/chat/how-tos/bot-dialogs?hl=en

"action_response": {
                "type": "DIALOG",
                "dialog_action": {
                    "action_status": "OK"
                }
            }

Here is what the bot is returning despite a 200 status returned, after the timeout -

Unlike other message types, button clicks expects additional details to be sent in the response. It needs to respond with NEW_MESSAGE or UPDATE_MESSAGE. Like this.

{
  "actionResponse":{
    "type":"UPDATE_MESSAGE"
  },
  "cards":[
    {
      "header":{
        "title":"Hello World!"
      },
      "sections": ...
    }
  ]
}
