where is the API support documentation? need help adding code to a code snippet

so halfway down the links to JS API Overview and Code Generator return a 404 error. i did leave a message with the customer support sales side of things on divimode.com.

what I need help with is adding some code to a snippet i have that autoruns a video in a popup when the popup is triggered and it auto closes the popup when the video ends. however I have a couple of pages that also have a divi section background video. and im seeing some performance glitches. so i am aiming to add some code that pauses the background video when the popup is triggered.

I did find this snippet that pauses a background video on mouse hover so i think i am on the right track.

<script>
window.onload = function() {
let videoBg = document.getElementsByClassName('mejs-mediaelement')[0].firstElementChild.firstElementChild;
let bg = document.getElementsByClassName('et_pb_section_video')[0];
videoBg.pause();
bg.addEventListener('mouseover', function() {
videoBg.play();
});

bg.addEventListener('mouseleave', function() {
videoBg.pause();
});
}
</script>

so this tests out good on my pages.

here is my code snippet

<script>

jQuery(document).ready(function ($) {
homeVideoElement1 = $("#divi-video-container1 video")[0];
homeVideoElement2 = $("#divi-video-container2 video")[0];
DiviArea.addAction('show_area', function(area) {
if (area.hasId('sim-intro')) {
homeVideoElement1.play();
}
if (area.hasId('libraryintro')) {
homeVideoElement2.play();
}
// console.log('im open');
});

$('video').on('ended',function(){
//console.log('Video has ended!');
$('a.da-close').trigger('click');
});
});

</script>

could someone help me with some code to add to my snippet to pause the background video?
