Go to Radeon Pro settings and go to the SweetFX section, hit enable, choose the folder with the SFX content, make a hotkey (i use scroll lock).
Add a profile for WD exe, go to sweetFX tab and hit enable, load the custom sweetFX watch dog config you downloaded by scrolling down and hitting import settings.
Don't forget to right click the profile and hit apply now. Launch game and it should launch with it on, if not hit your toggle. Also try enabling OSD to see if Radeon Pro is even working with the game, mine wasn't because I had the game with elevated privileges and RP was without. I couldn't elevate RP so I just unchecked admin rights for WD exe.
