My chrome extension is not working on Edge - google-chrome-extension

Question

I have a piece of code which works fine on chrome. I did the following step mentioned here.
I'm able to load it properly, but the code doesn't run properly.
In the background console only the url gets printed, no other consoles or alerts work.
Please any help will be appreciated ! Please
window.onload = function() {
console.log("blah1");
var port = browser.runtime.connect({name: "knockknock"});
port.postMessage({request: "sendData"});
port.onMessage.addListener(function(msg) {
console.log("blah2");
if(msg != null){
}
});
}
var sendData = null;
var url = null;
browser.webRequest.onBeforeRequest.addListener(function(details) {
if(details != null && sendData == null && details.url.includes("www")){
console.log(details.url);
sendData = details.url;
}
},
{urls: ["<all_urls>"]},
["blocking", "requestBody"]
);
browser.runtime.onConnect.addListener(function(port) {
console.log("inside addListener")
port.onMessage.addListener(function(msg) {
if (msg.request == "sendData"){
console.log("sendData : ", sendData);
port.postMessage(sendData);
}else if (msg.answer == null){
sendData = null;
}
});
});

I tested and found that if we remove window.onload then the extension will work well in Edge Legacy. It will print all the consoles.
You could set content.script run at document_idle. It's equal to window.onload and you do not need to listen for the window.onload event. For more detailed information, you could refer to this article.
My manifest.json is like below:
{
"manifest_version": 2,
"name": "test",
"version": "1.0.0",
"author": "medha",
"icons": {
"48": "esso.png"
},
"content_scripts": [
{
"matches": ["<all_urls>"],
"run_at": "document_idle",
"js": ["content.js"]
}
],
"background": {
"scripts": ["background.js"],
"persistent": true
},
"permissions": [ "webRequest", "webRequestBlocking", "webNavigation", "tabs", "<all_urls>", "storage"],
"-ms-preload": {
"backgroundScript": "backgroundScriptsAPIBridge.js",
"contentScript": "contentScriptsAPIBridge.js"
}
}
