headless screenshot with delay

I'm trying to write a script that would have firefox take a screenshot from the command line, in headless mode (I think). Only issue is that the site I'm trying to screenshot takes a couple of seconds to finish loading, so I only get a partially loaded screenshot. The only option available on the command line is --window-size...

I can take a screenshot inside the dev console with many more options, including --delay (https://developer.mozilla.org/en-US/docs/Tools/Taking_screenshots), is there any way to replicate these options on the command line?

Any other suggestions to script taking a screenshot of a site with delay added?

Did you look at Firefox in headless mode?

That's what I meant by "on the command line". Headless would have been a much better way to refer to it :)

In headless mode, there is only the option of setting the viewport size, but nothing else related to screenshots. I'd like to set a delay, just as it's possible inside the dev tools console.
