FDCAN between two STM32H747 MCU boards

I would be interested in implementing a FDCAN communication between two STM32H747 MCU boards.

I have implemented communication on a single board in External LoopBack mode. However, I am having problems understanding how to connect the two boards.

Do any of you know how to do this, or do you know a good guide?
