HELP Please, Generic Joystick

I just purchased a generic joystick and want to use it for Killer Instinct. I am on windows 10 and it says the device is connected.

However, when I open the game, it does not allow me to select the gamepad option in the top left corner next to the keyboard icon.

How do I use the joystick? The controller options setting are all keyboard keys.

The Windows 10 version of the game expects XBox One format inputs. You can use XOutput to convert formats.

I downloaded the XOutput, then it ask me to download ViGEm which I did as well.

Are there any instructions as to how I can set this up. I am a complete noob to all of this.
