Allow interactive message button clicks to edit buttons on message
Currently, when a user clicks on an interactive message button, MM sends a request to a remote web server with some information. When the server responds, it can send in a Message json blob, but this does not allow you to change the buttons on the message.
For example, if I were making a poll integration, there might be vote buttons, and after voting, I might update the button message to thank the user, and present them with the options to see the results or hide the message. Currently this is not possible.
According to the Polling example of the Interactive Message Buttons (beta), it's already possible to change the buttons.
