The app has Assets.xccassets/AppIcon and shows a nice icon in the dock.

But an NSAlert just shows a boring alert-triangle.
I want it to display the icon of my app instead.

So I did:
NSImage *myAppImage = [ [NSApplication sharedApplication] applicationIconImage ];
NSLog(@"%s myAppImage: %@", __FUNCTION__, myAppImage);

myAppImage: <NSImage 0x60000007cb40 Size={128, 128} Reps=(

[alert setIcon: myAppImage];

And now I get an even more boring default app image (paper with 2 pencils).
I really want the nice app image as shown in the dock.

There must be a simple answer (which becomes immediately obvious once known) to this.
