Something like this. Requires the custom calendar display site to host the images

I found this library: https://github.com/sindresorhus/capture-website

We can easily take a screenshot with:

import captureWebsite from "capture-website";

captureWebsite.file(
  "https://some-url-here.com",
  "calendar_screenshot.png",
  { inputType: "url" }
);
