Is there meant to be a way to interact with ExposedDropdownMenuBox using just the keyboard? I'm using it like this (simplified):

ExposedDropdownMenuBox(expanded = expanded, onExpandedChange = { if (enabled) {expanded = it }}) {
    OutlinedTextField(
        value = dropdownValue,
        onValueChange = {},
        modifier = Modifier.menuAnchor(ExposedDropdownMenuAnchorType.PrimaryNotEditable),
        enabled = enabled,
        readOnly = true,
        label = { stringResource(R.string.dropdown_name) },
        trailingIcon = { ExposedDropdownMenuDefaults.TrailingIcon(expanded = expanded) },
        colors = ExposedDropdownMenuDefaults.outlinedTextFieldColors(),
    )
    ExposedDropdownMenu(expanded = expanded, onDismissRequest = { expanded = false }) {
        dropdownItems.forEach {
            DropdownMenuItem(
                text = { Text(it) },
                onClick = {
                    dropdownValue = it
                    expanded = false
                },
                contentPadding = ExposedDropdownMenuDefaults.ItemContentPadding,
            )
        }
    }
}

But there doesn't seem to be any way to open the dropdown using just the keyboard - I can focus the field but no keys will open the dropdown (tapping it does open it).
