Vercel: cache-control for images

Is it possible to add cache-control headers for images when delpoying to Vercel? It doesn’t seem to work out-of-the box with the default vercel.json file from the documentation. image files seem to get a max-age=0 as cache-control header.

What should I add to vercel.json to add cache-control for files like png, jpg and svg, coming from the wp-content folder?
