Broken hot shoe for Canon 5D Mk III

I dropped my Canon 5D MkIII camera on the ground while it was attached to my speedlite transmitter (Godox X Pro). Luckily, the camera and lens was okay EXCEPT that the transmitter ripped the hot shoe off the camera. I have reattached the hot shoe but it’s no longer working properly.

After googling and testing I’ve concluded that the hot shoe is broken somehow but that the speedlites and triggers are all working properly. The hot shoe only works to trigger the light when a speedlite is directly attached to it (it fires when I hit the shutter) but the camera no longer recognizes the speedlite in the camera’s menu settings.

I have triple checked that it’s not just about how secure the hot shoe connection is. In other words, I am confident that this has nothing to do with a loose hot shoe mount. I have tested this in various ways and tightened everything several times to make sure.

(And yes I have tested several times that the transmitters and speedlites to make sure they work properly.)

I think that this means that the trigger element* works (pin? Element? Not sure what to call it, there are several metal connectors on the hot shoe). But one of the OTHER metal elements is broken.

Which finally (sry for long message) leads me to my questions:

Which element on the hot shoe is the one that sends intelligent / specific info from the transmitter to the speedlite? Perhaps if I know which it is I can find a way to fix it?

Any thoughts, advice, knowledge, is supper helpful.

THANK YOU!
