Jetpack Compose : How to overlay Composable with AndroidView?

I'm new to Jetpack Compose and trying to figure out how to solve next task:

I need to create a simple transparent AndroidView. And it needs to be used as an overlay for Composable functions.

The problem is that an overlay should be the same size as a compose view under it.

I had some-kind of successful attempt with this:

@Composable
fun BugseeOverlayView() {
    AndroidView(
        modifier = Modifier.fillMaxSize(),
        factory = { ctx ->
            View(ctx).apply {
                layoutParams = LinearLayout.LayoutParams(200, 200) //Hardcoded size
                alpha = 0.0F
            }
        }, update = {
            Bugsee.addSecureView(it) // 3rd party I need to use
        }
    )
}

And then I used it like:

Box {    
    Box(Modifier.fillMaxSize()) {
        BugseeOverlayView()
    }
    Text("Hide me") // or some 'CustomComposableView(param)'
}

This works, but the size is hardcoded.

PS. I need an AndroidView because of third-party tool which accepts android.view.View as a parameter.
