fun setFpContent(content: @Composable () -> Unit) {
        this.setContent {
            val sys = rememberSystemUiController()
            DisposableEffect(key1 = sys, effect = {
                sys.setStatusBarColor(Color.Transparent, true)
                onDispose { }
            })
            WindowCompat.setDecorFitsSystemWindows(window, false)
            Surface(
