So I tried Antimicro and it works well after some initial problems setting up.
Setup Antimicro:
Click "L Trigger" button in the app, change it to "Normal" if not already selected. Then click the [NO KEY] button to the right of "Normal".
Change it to Left Shift and close window backout to main menu
Repeat for "R Trigger" but select Right Shift instead.
Save it.
There may be other ways to set it up, I had a problem when I set the trigger to "Positive Throttle" mode first, as whilst it fired the flipper, it would stay up even after releasing button.
Note that you may need to run the Antimicro map as Administrator as per message at bottom of app window, I didnt need to.
