How to have a custom Pinterest Pin it or Save Button hover

Hey all. On Wordpress there are several plugins to create custom hover buttons for all images that you can pin. Is there any similar way to do this in Webflow?

After hours of searching - Nothing seems to work.

This seems almost there, but they never give an example of the code needed for a custom hover image.

Has anyone done this or know how it’s done? The stock red hover button is pretty atrocious. Let me know,

Thanks!
