How do I find the id of the vappTemplate given a vm object or vappTemplate?

Hi,

In VCD, I use a vappTemplate in order to create a VM.

Now after creating the VM, I need to retrieve the id of the vappTemplate from which this VM was created. But looking at the vm object (in the vmware vcd java sdk 5.1) I don't see it containing this vappTemplate information at all. How can I retrieve the id of the vappTemplate from which the VM was created?

Thanks,
