[FIXED] Google Maps inside Android Webview is not Loading

Issue

I have a React Web Application that has a camera and google maps embedded in it. I have hosted this in Netlify and have a link for it.

I'm implementing Android Webviews with the above link in java. I got the camera working but the map isn't loading.

I tried all the ways and saw many StackOverflow questions and I implemented the same but was still not able to load google maps.

Below is the MainActivity.java code
