As per Documentation Write Operation should work but not working

[naparam]

As per documentation and below example should properly in Kotlin Multi platform but it's not working Why
// plain old kotlin object
val person = Person().apply {
name = "Carlo"
dog = Dog().apply { name = "Fido"; age = 16 }
}

// persist it in a transaction
realm.beginTransaction()
val managedPerson = realm.copyToRealm(person)
realm.commitTransaction()

// alternatively we can use
realm.beginTransaction()
realm.create().apply {
name = "Bar"
dog = Dog().apply { name = "Filo"; age = 11 }
}
realm.commitTransaction()
