`safetyNetToken` missing in identitytoolkit_v3

In the [REST API documentation](https://cloud.google.com/identity-platform/docs/reference/rest/v1/accounts/sendVerificationCode) of Identity Platform, it's mentioned that we can pass a safetyNetToken argument to `sendVerificationToken` for android devices.

This argument is not missing from the [`Schema$IdentitytoolkitRelyingpartySendVerificationCodeRequest`](https://github.com/googleapis/google-api-nodejs-client/blob/main/discovery/identitytoolkit-v3.json#L871-L893) interface, when other platform-specific arguments are specified.

Is it intentional? Is there something I'm missing? Is v3 a new version of the Identity Platform API that doesn't support this argument anymore?

Also `verifyIOSClient` is missing, but it's needed to be able to provide the iosReceipt and iosSecret requested in this method right?
