Before (Deprecated)

  var balloonWindow: BalloonWindow? by remember { mutableStateOf(null) }

  Balloon(
    builder = builder,
    onBalloonWindowInitialized = { balloonWindow = it },
    onComposedAnchor = { balloonWindow?.showAlignTop() },
    balloonContent = {
      Text(text = "Tooltip content")
    },
  ) {
    Button(onClick = { balloonWindow?.showAlignTop() }) {
      Text(text = "Show Balloon")
    }
  }

After (New API)

  val balloonState = rememberBalloonState(builder)

  LaunchedEffect(Unit) {
    balloonState.showAlignTop()
  }

  Button(
    modifier = Modifier.balloon(balloonState) {
      Text(text = "Tooltip content")
    },
    onClick = { balloonState.showAlignTop() },
  ) {
    Text(text = "Show Balloon")
  }
