In Type.kt Typography I defined h1 TextStyle like this:

h1 = TextStyle(
     fontFamily = FontFamily.SansSerif,
     fontWeight = FontWeight.W500,
     fontSize = 70.sp,
     color = Color(0xFFF8F9FC)
),

Now how can I define the Text widget to be an h1 so these TextStyles applies automatically?

If you plan on using your style globally for all text that you want identified as h1, you should create a custom composable for that and apply your style there:

@Composable
fun TextH1(
   text: String,
   modifier: Modifier = Modifier
) {
   Text(text = text, modifier = modifier, textStyle = h1)
}

Alternatively, you could use CompositionLocal, but that tends to become cumbersome if used extensively.

You can get the current theme h1 from any @Composable with MaterialTheme.typography.h1, so your widget might look like this:

@Composable
fun TextH1(
    text: String,
    modifier: Modifier = Modifier,
) {
    Text(
        text = text,
        modifier = modifier,
        style = MaterialTheme.typography.h1,
    )
}
