我试图通过Android Jetpack compose中的collect将消息从viewModel传递到我的Screen Activity中，在那里我试图显示snackbar，但由于某种原因，它没有改变snackbar上的背景颜色和操作按钮颜色（也没有进入if条件），并且它也没有与我传递的字符串进行比较，并且总是进入else条件。请建议如何从活动屏幕处理此场景

// From ViewModel

private val _showMessage = MutableSharedFlow<String>()
val showMessage get() = _showMessage.asSharedFlow()
_showMessage.emit("My custom message")

// From ViewController Activity

val scaffoldState: ScaffoldState = rememberScaffoldState()

SnackbarHost(scaffoldState.snackbarHostState) { data ->
    // custom snackbar with the custom colors
    Snackbar(
        actionColor = Color.Blue,
        backgroundColor = Color.Gray,
    )
}

LaunchedEffect(scaffoldState.snackbarHostState) {
    viewModel.showMessage.collect {
        if (viewModel.showMessage.equals(“My custom message”)) {
            scaffoldState.snackbarHostState.showSnackbar(it, "OK", SnackbarDuration.Indefinite)
        } else {
            println("view message ${viewModel.showMessage.equals("My custom message”)}”).  /// Coming as false always
            scaffoldState.snackbarHostState.showSnackbar(it)
        }
    }
}
