Where to Get the Xhorse Condor II Engraving Cutter?

I bought the xhorse condor xc-mini plus ii key cutting machine to do engraving. It asks for a special engraving cutter. Where and what engraver bit do I buy?
It will not engrave without the engraver cutter? Do you not know when it will be available?
Xhorse Condor Ii Engraving Cutter
The engraving cutter is an optional accessory of condor ii.
It is not yet available now. You will be informed once it is in stock.
FYI: the M5 clamp is used to cut vehicle keys, to cut dimple key and engrave key, you need optional clamp/cutter separately.
