Contacts available during transfer

I know an option was just added to add contacts to a line key in order to use the contacts to transfer calls. However, I am still not seeing the option. Do I need to update the phone or any other modules? I’m on Endpoint Manager 13.0.51 and Phone Apps 13.0.34.

I only have the option “REST - Contacts” in the Idle section of my horizontal soft keys.

Thanks,

Pick XML-API then you can pick contacts

Thank you very much!
