How to use the @tanker/identity._deserializePublicIdentity function in @tanker/identity

const expectMatchingPublicIdentities = (identityA: string, identityB: string) => expect(
    _deserializePublicIdentity(identityA),
  ).to.deep.equal(
    _deserializePublicIdentity(identityB),
  );

const expectMatchingPublicIdentities = (identityA: string, identityB: string) => expect(
    _deserializePublicIdentity(identityA),
  ).to.deep.equal(
    _deserializePublicIdentity(identityB),
  );

const toPublicIdentity = async (identity): Promise => {
      const publicIdentity = await getPublicIdentity(identity);
      return (_deserializePublicIdentity(publicIdentity): any);
    };
    const toPublicIdentities = (list): Promise> => Promise.all(list.map(toPublicIdentity));

    const deserializedIdentities = publicIdentities.map(i => _deserializePublicIdentity(i));
    const { permanentIdentities, provisionalIdentities } = _splitProvisionalAndPermanentPublicIdentities(deserializedIdentities);

    const deserializedIdentities = (sharingOptions.shareWithUsers || []).map(i => _deserializePublicIdentity(i));
    const deserializedIdentitiesWithSelf = this._handleShareWithSelf(deserializedIdentities, shareWithSelf);
