FC Blitz Mini F7 & DJI o4 wiring

Hello,

Total beginner here getting into FPV. I'm currently trying to build a Nazgul Evoque V3, but I'm running into an issue with wiring my flight controller to the DJI O4 Pro unit.
FC: Blitz Mini F7 > 9-pin port
Air Unit: DJI O4 Pro > 6-pin port

I only have the stock 6-to-6 pin O4 cable. Does anyone know what specific cable or adapter I need to order to bridge the 9-pin FC to the 6-pin O4 please?
