I thought this was one of the advantages of Godox - my understanding was that the camera brand specific trigger decoded the camera brand specific flash protocols, and converted them to a common 'Godox' protocol, which it then transmitted to the Godox receiver (usually built in). The decoding of the individual camera brand TTL or HSS protocols is done in the trigger - which has to be brand specific, and allows the receivers to be generic.
So a Nikon fit trigger can (for example) fire a Nikon fit Godox flash, a generic unit (EG AD-200) or a cross brand fit Godox Flash (EG Canon fit Godox Flash).
What you cannot do is use a cross brand trigger - so a Nikon fit trigger will either not fire, or give manual only, if used on anything other than a Nikon camera.
Note: I may be mistaken in this - it's not something I've personally tried, but I am reasonably sure that this was the case, and it's been said a number of times.
