.width(24.dp),
contentAlignment = Alignment.Center
) {
...

Spacer(Modifier.width(8.dp))
Column(modifier = Modifier
.onGloballyPositioned { layoutCoordinates ->
columnHeight =
with(density) { layoutCoordinates.size.height.toDp() }
}
.fillMaxWidth(),
verticalArrangement = Arrangement.spacedBy(8.dp)) {
...
