IdentitySet class does not have 'phone' property

Describe the bug

When trying to make a phone call, I specify the IdentitySet of the Target user like this:

    targets = [
        InvitationParticipantInfo(
            identity = IdentitySet(
                phone = Identity(
                    id = "+mynumber"
                )
            )
        )
    ]

However I get the following error "IdentitySet.init() got an unexpected keyword argument 'phone'" stating that this parameter is not available for the IdentitySet class.
This works when calling from the rest API

Expected behavior

Parameter should be present in the class, just like the user parameter for calling an teams userid

How to reproduce

target_identity = IdentitySet(phone=Identity(id=graph_p.phone_number))
target = InvitationParticipantInfo(
    identity = target_identity
)
request_body = Call(
    callback_uri = "myballback",
    tenant_id = tenant_id,
    source = ParticipantInfo(
        identity = IdentitySet(
            application = Identity(
                id = bot_instance_id
            )
        )
    ),
    targets = [target],
    requested_modalities = [Modality.Audio],
    media_config = ServiceHostedMediaConfig(
        pre_fetch_media = []
    )
)

IdentitySet モデルのエントリポイントから開始し、issue にある IdentitySet(phone=Identity(...)) の構築を再現します。サポートされているコンストラクタパラメータを REST API の形状と比較し、additional_data を使わずに phone ターゲットを生成されたリクエストボディで表現できることを確認します。
