Is there a way to invert PointerLockControl's horizontally and not vertically?

hello!
I know there is a setting to set the speed that it affects the camera, but setting it to -1 sadly also affects it vertically, i was wondering if there was a simple way to invert the horizontal movement only?

The euler that controls this movement is not exposed, you’ll likely have to fork the class and make the required changes…

          // event listeners
          
          function onMouseMove( event ) {
          
          	if ( this.enabled === false || this.isLocked === false ) return;
          
          	const camera = this.object;
          	_euler.setFromQuaternion( camera.quaternion );
          
          	_euler.y -= event.movementX * _MOUSE_SENSITIVITY * this.pointerSpeed;
          	_euler.x -= event.movementY * _MOUSE_SENSITIVITY * this.pointerSpeed;
          
          	_euler.x = Math.max( _PI_2 - this.maxPolarAngle, Math.min( _PI_2 - this.minPolarAngle, _euler.x ) );
          
          	camera.quaternion.setFromEuler( _euler );
          
          	this.dispatchEvent( _changeEvent );
          
          }
