Unity 2020.1 sendMessage no longer works from browers JS

Hi, If you want to create your own web template: https://docs.unity3d.com/2020.1/Documentation/Manual/webgl-templates.html][1]

Go to Unity WebGL templates folder (the path folder is in the link above) and I copied default template folder to my project in Assets/WebGLTemplates/MyFirstTemplate folder.

Unity WebGL has this code by default:

  var  unityGame; //This mine
  var script = document.createElement("script");
       script.src = loaderUrl;
       script.onload = () => {
         createUnityInstance(canvas, config, (progress) => {
           progressBarFull.style.width = 100 * progress + "%";
         }).then((unityInstance) => {
 
           unityGame = unityInstance; //This mine
 
           loadingBar.style.display = "none";
           fullscreenButton.onclick = () => {
             unityInstance.SetFullscreen(1);
           };
         }).catch((message) => {
           alert(message);
         });
       };

The var unityGame; and the unityGame = unityInstance; lines are mine, you can use the variable name you want, with this I ensure the var is instantiated properly wihen the Unity Engine be ready.

And finally use this to send messages to my function MyHelloPublicFunction in my c# file "whatever.cs":

 unityGame.SendMessage( "MyObjectCreatedInUnityEngine", "MyHelloPublicFunction", "Hello world" );
