Maintain aspect ratio of icons in a componet

Hi, I am using components for the first time with properties. I have a card with text and an icon. The icons have been configured as Instance properties, but the icons I have all have differing sizes. Is it possible for the icon to maintain its aspect ratio, as presently it does not and loos stretched. I tried to place the icon in a frame but that didn’t appear to help.

Thanks in advance.
