Keyboard steering using Advanced Gamepad Assist or A7 Assist V1 does not work

Bought og Assetto Corsa on the recent Steam sale, and I've been trying to get my keyboard experience to be a lot smoother since I don't own a wheel or a working gamepad.

I've tried using Advanced Gamepad Assist 1.5.5, and A7 Assist V1, with "Drift by Frans Gaming Low" preset for Keyboard Splitter, but both of them for some reason doesn't let me steer the wheel with A and D.

I suspect this has something to do on Keyboard Splitter's end but after experimenting I still can't figure it out. Need help with this.

Content Manager and CSP is up to date that on latest recommended build, and yes Gamepad script is ticked Active under CSP's Gamepad FX, and "combine with keyboard" is ticked under Assetto Corsa settings. Keyboard steering also works fine if I use "Keyboard & mouse" instead of "Gamepad" as my input method under Assetto Corsa settings.
