Grafana K6 - Real time Dashboard Export PDF?

Can you please help to export pdf too, K6_WEB_DASHBOARD_EXPORT=load-test.html or using K6 screenshot for load-test.html in headless mode. currently both cases are not helping us. K6 browser screenshot can be taken, but it’s not showing the Graph plots, we can see only tables, icons,. We cannot use html for proof of certification.
