Hide messages from attached buttons in chats

How to hide text which send as action to click on attachments chat buttons like:

"attachments": [
      "actions": [
          "type": "button",
          "text": "Btn1 Title",
          "msg": "Btn1 message",
          "msg_in_chat_window": true

In this case when user click on button Btn1 Title i receive in chat window “Btn1 message”. Is it possible to hide this text for chat?
Tried to set msg_in_chat_window to false, but in this case button interface maked hidden.
