I have an SVG file made by someone else, which I'd like to insert into Powerpoint such that its background (the white pixels in the image below) appears transparent and reveals the content in the layer below.
Exporting the SVG as PNG in Inkscape 1.2.1 doesn't result in an image with transparent background. Likewise if I convert to PNG using converters available online.
I found various suggestions on this site for how to remove backgrounds in Inkscape for SVGs, e.g. tick the Checkerbox option under Document Properties, or doing a Select All + Ungroup; but none worked.
Image preview is below, SVG file is here.
