использовать компонент навигации:

@Composable
fun de(){
    val navController = rememberNavController()
    Scaffold { innerPadding ->
        NavHost(navController, "home", Modifier.padding(innerPadding)) {
            composable("home") {
                // This content fills the area provided to the NavHost
                val saveDialogState = remember { mutableStateOf(true) }
                Button(onClick = {
                                 navController.navigate("detail_dialog")
                }, modifier = Modifier.testTag(PLACE_TAG)) {
                    Text(text = "helllow")
                }
            }
            dialog("detail_dialog") {
                // This content will be automatically added to a Dialog() composable
                // and appear above the HomeScreen or other composable destinations
                
        Dialog(onDismissRequest = {navController.navigate("home")}) {
        Card(
            shape = RoundedCornerShape(10.dp),
            modifier = Modifier
                .fillMaxWidth()
                .wrapContentHeight()
//                    .padding(horizontal = 16.dp)
                .padding(vertical = 8.dp),
            elevation = 8.dp
        ){
        Text(text = "helllow", modifier = Modifier.testTag(BUTTON_TAG))
        }
    }
            }
        }
    }
