You shouldn't do it like that. Now I don't want to play this script where you ask A and I tell you to do B, don't worry, but it's really not the way you should do it.

You should make cordova load an index.html which loads a javascript file cordova.js. You don't need to actually have it, the js file will be included when you compile the app.

Then you should add the whitelist plugin in case you don't already it, in order for your website to load correctly. https://www.npmjs.com/package/cordova-plugin-whitelist

You should disable auto-hide for the splashscreen in config.xml like so:

<preference name="AutoHideSplashScreen" value="false" />

You should then make the javascript load a fullscreen iframe with your website like so, then detect when loading has finished: (This should go into your index.html, in the cordova app)

<html>
    <head>
        <title></title>
    </head>
    <body>
        <iframe id='frameid' onload='iframeLoaded();' src='https://mywebsite.com/mypage.html' style='border: 0; width: 100%; height: 100%'>Your browser doesn't support iFrames.</iframe>
        <script src='cordova.js'></script>
        <script>
             iframe = document.getElementById("frameid");
             
            iframe = document.getElementById("frameid");
            
            function ready(callback){
                // in case the document is already rendered
                if (iframe.readyState!='loading') callback();
                // modern browsers
                else if (iframe.addEventListener) iframe.addEventListener('DOMContentLoaded', callback);
                // IE <= 8
                else document.attachEvent('onreadystatechange', function(){
                    if (iframe.readyState=='complete') callback();
                });
            }
            
            ready(function(){
               setTimeout(function(){
                 navigator.splashscreen.hide();
               },555)
            });
             
      
      
        </script>
    </body>
</html>

I haven't used cordova for a few months but that's how I did it if I didn't forget anything - Hoping I didn't... I didn't have time to test this, but you get the gist:

App start
Show Splashscreen
Load Index.html with Iframe in fullscreen pointing to https website.
Wait for iframe to finish loading.
Close splashscreen

Tell me if you run into any issue and I can help you further.
