What do you think, did I implement it right?

@Composable
val composableScope: CoroutineScope
    get() {
        val context = SupervisorJob() + Dispatchers.Main.immediate
        onDispose {
            context.cancel()
        }
        return CoroutineScope(context)
    }

Or maybe there is out-of-the-box solution?
