        setContent {
            MyApplicationTheme {
                Column(

                    modifier = Modifier
                        .fillMaxWidth()
                        .fillMaxHeight()
                        .padding(20.dp)) {
                    Card(
                        elevation = 4.dp,
                        shape = RoundedCornerShape(20.dp)
                    ) {
                        Column(modifier = Modifier.padding(10.dp)) {
                            Text("AB CDE", fontWeight = FontWeight.W700)
                            Text("+0 12345678")
                            Text("XYZ city.", color = Color.Gray)
                        }
                    }
                    Spacer(modifier = Modifier.height(30.dp))
                    Card(
                        elevation = 4.dp,
                    ) {
                        Column(modifier = Modifier.padding(10.dp)) {
                            Text("AB CDE", fontWeight = FontWeight.W700)
                            Text("+0 12345678")
                            Text("XYZ city.", color = Color.Gray)
                        }
