Changing Icon of Application in IntelliJ with Java Swing on MacOS

[fallow flame]

Why does the icon of my app not change with IntelliJ on Mac? I find Swing to barely change anything on Mac, like the title bar. Here is the code I'm using:

    frame = new JFrame("File Uploader");
    ImageIcon appIcon = new ImageIcon("src/assets/IMGs/MetaTune_Icon.png");
    if (appIcon.getImageLoadStatus() == MediaTracker.COMPLETE) {
        System.err.println("Loaded image: ");
    }
    frame.setIconImage(appIcon.getImage());

I get no errors and I also get "loaded image" but no changes.

Please format your code to make it more readable.
For java, it should look like this:
```​​​`​java
public void foo() {

}
​​​`​```

Also consider using new ImageIcon(getClass().getClassLoader().getResource("assets/IMGs/MetaTune_Icon.png")) instead of new ImageIcon("src/assets/IMGs/MetaTune_Icon.png")
