android - Firestore DocumentReference Serialization

Question

I have a pojo which maps a firestore document. That document contains references to other documents of other collection.

class Game(var local: String? = null, var visitor: String? = null,
        var events: MutableList<DocumentReference> = mutableListOf(), var date: Date? = null): Serializable 

The problem is that DocumentReference isn't serializable. I've read that I can save the path as String and then create the object myself(FirebaseFirestore.getInstance().document(path)), but then in the firestore is no longer a field of type Reference.

So my question, Is this the good approach? Also, Does it matter that the field is a String rather than a Reference?
