Where to Add Machines as Products to Map with Assets in Zoho FSM?

implementing Zoho FSM for a clinical equipment supply company.
The business sells and installs clinical machines in hospitals and clinics, and they also handle service requests, scheduled maintenance, calibration visits, and general machine upkeep.

In Zoho FSM, we are not sure where to add the machines themselves as products so that they can be mapped to Assets.
In the Services and Parts module, we already added the service items and spare parts for each machine, but we still don't understand where the actual machine (main equipment) should be created.
