I have a bunch of conditionals here. Is there any way to simplify this? Also, if you could, could you explain what the '?' in 'migrated.value?.user' means? Thanks

 {migrated.value === null ||
  migrated.value?.user === null ? null : migrated.user
      ?.migrated_to_new_login === null ||
    migrated.user?.migrated_to_new_login === 0 ? null : (
    <MigratedToNew
      passwordValue={passwordValue}
      setPasswordValue={setPasswordValue}
    />
  )}
