HTML2Canvas how to screenshot a map?

Question

JavaScript

Good day.
Task: we manipulate the map and make a screenshot of the map by the button so that our changes are visible in the screenshot.

Installed html2canvas, but there is a problem, it makes a screen, and where the map should have been a large white square.
It is clear that he will not screen content from third-party resources. But how would you get around this? Or similar plugins?
