I have few doubt using viewmodel in composable function. I am adding my activity code, I am passing my intent bundle.
1. So I want to ask is this best practise to use viewmodel like this to create viewmodel global in the activity?

InputActivity.kt

class InputActivity : ComponentActivity() {

    private val viewModel by viewModel<InputViewModel>()

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setupViewModel()
        setContent {
            Theme {
                AppBarScaffold(
                    displayHomeAsUpEnabled = true,
                    titleId = R.string.personal_health
                ) {
                    viewModel.OptionData?.let {
                        Input(it)
                    }
                }
            }
        }
    }

    private fun setupViewModel() {
        viewModel.optionData = intent.getParcelableExtra("optiondata")
    }
}

I have so many composable function
Input

@Composable
fun Input(optionData: OptionData) {
    var value by rememberSaveable {
        mutableStateOf(false)
    }
    Column(
        modifier = Modifier
            .fillMaxHeight()
            .verticalScroll(rememberScrollState())
        verticalArrangement = Arrangement.SpaceBetween
    ) {
        InputItem()
        Spacer()
        OnSubmitPulse()
    }
}

InputItem

@Composable
fun InputItem() {
    Image()
    PulsePressure()
}

PulsePressure

@Composable
fun PulsePressure() {
    Column {
        InputWithUnitContainer()
        InputWithUnitContainer()
    }
}

InputWithUnitContainer

@Composable
fun InputWithUnitContainer() {
    Row() {
        Text()
        TextField(value = "")
        Text()
    }
}

Every function have logic which I want to store in viewmodel.
1. So should I create viewmodel in constructors parameters or pass viewmodel instance every time ?
Scenario 1

fun Input(optionData: OptionData,viewModel: InputViewModel = viewModel())

and

fun InputItem(viewModel: InputViewModel = viewModel())

and

fun PulsePressure(viewModel: InputViewModel = viewModel())

Scenario 2

fun Input(optionData: OptionData,viewModel: InputViewModel = viewModel()) {
        InputItem(viewModel)
}

and

fun InputItem(viewModel: InputViewModel) {
      PulsePressure(viewModel)
}

and

fun PulsePressure(viewModel: InputViewModel) {
    // more function call
}

So what would you guys suggest in jetpack compose. Please ask me if you don't understand me question. Many Thanks
