A screenshot taken from ARScreen shows black

[Settasit7]

I'm trying to make a button to take a screenshot using this following code, but the image shows black color on ARScreen part.
How do I make it work?

fun Activity_3() {

    ...

    val context = LocalContext.current
    val view = LocalView.current

    ...

    saveScreenshot(context, view.drawToBitmap())

    ...

}

fun saveScreenshot(context: Context, bitmap: Bitmap) {
    val contentValues = ContentValues().apply {
        put(MediaStore.Images.Media.DISPLAY_NAME, "screenshot_${System.currentTimeMillis()}.png")
        put(MediaStore.Images.Media.MIME_TYPE, "image/png")
        put(MediaStore.Images.Media.RELATIVE_PATH, Environment.DIRECTORY_PICTURES)
    }
    val contentResolver = context.contentResolver
    val uri = contentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)
    if (uri != null) {
        contentResolver.openOutputStream(uri).use { outputStream ->
            if (outputStream != null) {
                val isSuccess = bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream)
                if (isSuccess) {
                    Toast.makeText(context, "Screenshot saved!", Toast.LENGTH_SHORT).show()
                } else {
                    Toast.makeText(context, "Failed to save screenshot.", Toast.LENGTH_SHORT).show()
                }
            }
        }
    } else {
        Toast.makeText(context, "Unable to create URI.", Toast.LENGTH_SHORT).show()
    }
}
