KQL plugin : how to get the image URL from the image block?

I also have the same question. I use kirby headless so I would like to get the file url.

Is there a way to change what the image block returns?
I think one way would be to write my custom block (Creating a custom block type from scratch | Kirby CMS) where I define that return values should include the fill image path (also giving me the power to resize and crop the images how I want).

But if I could just override and customize the default image block type, that would be even better…

Thanks for any thoughts about that idea.
Cheers
