                                LaunchedEffect(Unit) {
                                    balloonWindow.showAlignTop()
                                }
                            }
                        })
                    }
                ) {
                    Greeting(modifier = Modifier.padding(it), name = "Android")
                }
            }
        }
    }
}

@Composable
fun Greeting(name: String, modifier: Modifier = Modifier) {
    Text(
        text = "Hello $name!",
        modifier = modifier
    )
}

Screenshot attached.

You should use setArrowElevation inside of the builder.

Also, the elevation will be only applied when the arrow is towards the bottom.
Because the arrow is placed on the body of the balloon, elevation will invade the body, and that will look weird.

Hmm, I tried that and ran into #159 and #156. Is that the reason why the default for the bubble elevation and arrow elevation are not the same?
