How to use Received Transport in conditions?

How do I make a rule match when kMDItemUserSharedReceivedTransport includes com.apple.AirDrop?
I regularly export OPML files from a podcast player app on iPhone, which opens a share sheet where the quickest way to get them to the Mac is AirDrop. Because the filename is very common, I want to make sure Hazel only works on those.
