How to set height to an element by his background image height - css

Question

Hi I have this component in my app, Right now the height of this ButonBase is hard coded.
I get an image from backend and I set that image as a backgroundImage for the ImageImagine component.
I need to make height of that ButonBase to bee dinamic so the background image in imageImagine can mentain original aspect ratio.

Had you tried to set the height of the ButtonBase into height: auto and the min-height into min-height: fit-content?
