Works perfectly! Initially it only supported Microsoft Defender and not Barracuda (https://linkprotect.cudasvc.com/...), which is the one used at my institution. I contacted the author and he kindly adapted the code to work with both (this version is currently beta but I am sure it'll soon make it into the main release). The implementation is open source and is made of a relatively simple code base that is easy to check so one can accept with confidence the few permissions needed. Overall a simple yet very useful extension that just works.
