Get the Zendesk JWT for the mobile app

**Deprecated:** Use `/api/v2/my/helpdesk/zendesk/auth/messaging` instead. Use this method to generate the JSON Web Token (JWT) for single sign-on (SSO) authorization in Zendesk from the mobile app. This enables a client to access the Zendesk functionality without any additional authorization.

curl -X POST "https://example.com/api/v2/my/helpdesk/zendesk/auth/mobile"
