USB PD enable display port [STM32N6 - SNK]

* board - STM32N6570-DK

*  using STM Cube 1.19.0

* Example - USBPD_SNK

 

Goal - to enable Display port

 

Problem - is i'm getting stuck with the current example.  It gets stuck at SVDM_deiscovery_identity part.  Which in that packet i should be able to start to tell the host that i have display port capability, but i what is currently set it that the message is unsupported.  How would i go about enabling this.

 

Thoughts - In usbpd_vdm_user.c it seems like it has all the stuff that i need to start sending back these kind of messages but they don't seem to be called anywhere.  

There's a function called

USBPD_VDM_DiscoverSVIDs()

But it doesn't seem to be called.
