Register a L2CAP PSM (Protocol Service Multiplexer) with BlueNRG library v1.0.0

Hi, I'm currently working with some STEVAL-IDB007V1 and very interested to establishing a L2CAP CoC (connection oriented channel) between those devices. From my understanding a L2CAP PSM channel must be registered with the BLE stack. As such the stack later on is able to accept an incoming L2CAP connection request, allowing establishment of a L2CAP CoC between devices.

I've spent some hours digging into the BlueNRG-1 library v1.0.0 but unable to find any indication that the library exposes such functionality.

Could anyone please confirm if my understanding is correct?

Thanks so much in advance!
