Button passes contrast test however button’s background and div’s background are low contrast

I have been going back and forth with design about this. I think there should be a contrast with the button and the div that holds the button, however, design says there is no rule about that. I try to research about this topic all around the internet and this is my last resource to find out about this. Here is an image that shows what I am talking about.

The button color and the text are accessible, however the background of the div and the background of the text have low resolution.

Please help and thank you in advance:
