TAdvWebbrowser - Custom Protocol Handler Possible?

Based on this code:
https://jasontpenny.com/blog/2010/03/23/custom-protocol-handler-in-delphi/
I was able to get it working with IE and it worked well at the time. I've been trying to figure out how to get custom protocol handler working with new Edge. Does anyone have any idea how to do it or if it's even possible.

Hi,

The current exposed APIs are very limited. We are following up on a weekly basis when and if Microsoft is exposing more APIs. At this point, it seems there is no way to handle this. We'll add this on our list for further investigation.
