How to Create a High-Resolution Sitemap for Google Slides

I’m trying to use this sitemap in a Google Slides presentation and no matter what I do I can’t get a good high resolution PNG to include. I’ve tried taking a screenshot of the sitemap but I have to reduce the zoom level so much that the text is really small and if I export it to Figma and Copy as PNG from there and paste it into Google Slides, the text is also unreadable. Any suggestions? I wish I could make the sitemap be vertical instead of horizontal and maybe it would fit better then?
