I tried the various methods I found as I am still learning and wish to update my previous question. I want a BottomSheetScaffold to display a file MailView.kt when a button is clicked.

But, it is still not showing up though there are no problems displayed, please.

The code for BottomSheetScaffold:

val scope = rememberCoroutineScope()
val bottomSheetScaffoldState = rememberBottomSheetScaffoldState()

  BottomSheetScaffold(
        scaffoldState = bottomSheetScaffoldState,
        sheetContent = {
            MailView(scaffoldState = bottomSheetScaffoldState)
        },
        sheetPeekHeight = 0.dp, // Ensure the sheet is hidden initially
        content = {
            // Your main content

        },

    )

Code for button:

Button(
onClick = {scope.launch {
bottomSheetScaffoldState.bottomSheetState.expand()
 }
 },

Code in MailView.kt

@OptIn(ExperimentalMaterial3Api::class)
@Composable
fun MailView(scaffoldState: BottomSheetScaffoldState) {
    val scope = rememberCoroutineScope()

    Column(
        modifier = Modifier
            .fillMaxWidth()
            .padding(16.dp)
            .background(Color.White)
    ) {
        Row(
            modifier = Modifier
                .fillMaxWidth()
                .padding(8.dp),
            verticalAlignment = Alignment.CenterVertically,
            horizontalArrangement = Arrangement.SpaceBetween
        ) {
            IconButton(onClick = {
                scope.launch {
                    scaffoldState.bottomSheetState.hide()
                }
            }) {
                Icon(
                    painter = painterResource(id = R.drawable.ic_close),
                    contentDescription = "Close",
                    tint = Color.Gray
                )
            }
            Image(
                painter = painterResource(id = R.drawable.logo_image),
                contentDescription = "Logo",
                modifier = Modifier.size(24.dp)
            )
            Text(
                text = "SOME HEADER...",
                fontFamily = customFontFamily,
                fontWeight = FontWeight.Bold,
                fontSize = 14.sp,
                color = Color.Black
            )
        }
        HorizontalDivider()


            // Use the WebViewPage composable here
            WebViewPage(url = "https://www.google.com") 
        }
    }
