| Parameters: | |
| y: List of lists representing the message and response pairs. Each message and response should be a string, which may be in Markdown format.

It can also be None, in which case that message is not displayed. | |

| List of lists representing the message and response. Each message and response will be a string of HTML, or a dictionary with media information. Or None if the message is not to be displayed. | |
