How to save image without overlay in fabric js?

Question

JavaScript

Good afternoon
There is an svg image in a certain form, which is set as overlay in fabric js

fabric.loadSVGFromURL(
            url,
            (objects, options) => {
                const background = fabric.util.groupSVGElements(objects, options);
                background.scaleToWidth(canvas.getWidth());
                canvas.setOverlayImage(background).renderAll()
            },
            null,
            {crossOrigin: 'anonymous'},
        );

And there is the main image that I position in the fabric js canvas
It looks like this:

After I need to save the image obtained behind the overlay (aunt in this case) without a black border
If I delete the overlay, then the "aunt" will be wider than necessary
Is it possible to save the image without overlay ?
