I sent you a reply in your BO1 thread but I forgot to mention a few things.
Open up DS4Windows and go to "Profiles" > "New" > "Yes".
Make sure your "Presets" are set to Gamepad and that "Output Controller" is Xbox 360 (this is if you want to access Xbox Gamebar from the PS button), choose apply.
Go to "Touchpad" and change output mode from "Mouse" to "Passthru" like I mentioned last time, name your profile something like "BO2" then select "Save".
Last but not least, select your new profile from the drop-down list as shown in the image below.
I hope this clears things up
