why do we care about the ownUserProperties here?

We don't want to remove those ownUserProperties ... they are kinda reserved fields!!

oh i see and they are not in the event object, in that case maybe we should extract these fields and put them somewhere as a source of truth, in future, if we add more reserve fields and forgot to add them here it will cause hard to find issues

hey maybe create a shallow copy of user and delete properties on it instead of deleting this.user[key] directly? this way we can only set this.user in the end of the function so we will only mutate it once instead of manually deleting the keys during the function execution.
this is useful to avoid half-updated states in case this function fails in the middle of its execution.
