Lex v2 How to display multiple images in an intent?

I need to display multiple images in a intent.
I see in the close response I can define a card group but only one card will be displayed

"You can define up to three cards per group. One of the cards is selected during a conversation."

How can I display multiple images in a intent? (Hopefully without having to call a Lambda function to do so)

~ Also having a hard time finding Lex V2 examples and have to check the dates of the post because I keep coming up with replies related to V1!

Thanks -
