Is there any means to make use of my cellphone + controller as PC controller?

So mainly, what I want is to make use of this Gamesir G8 Galileo controller with my Samsung cellphone, to behave as a controller to play Darkish Souls 3 on Home windows. Mine is a non-Steam recreation, so I've tried Steam Hyperlink and it didn't work.

I attempted Distant Gamepad however the joystick didn't work.

I attempted Moonlight Sport Streaming and Sunshine however couldn't join the cellphone to the PC.
