Handling Cinemachine Freelook Camera with Touch Input to pan

I've implemented Unity's Cinemachine and I can alter it's values through script (like value of axes etc). Now I was able to successfully control the free look camera using touch input to change camera's rotation in the X axis (left right).

However here's my problem. When I swipe to either left or right then stopped but didn't lift my finger, the camera continues to move to that direction after then stops at a certain point (I assume is stops to what my X values we're passed to). But when I swipe then lift my finger immediately, the camera stops rotating immediately as well. (Which is what I want to achieve when I swipe and kept my finger stationary, I also want the camera to stop if stationary)

here's my code below: (PS: TouchPhase.Stationary didn't worked or I might've used it wrong)

 foreach (Touch touch in Input.touches)
         {
             //override mouse x of camera
             if (touch.phase == TouchPhase.Began) //get first touch or current touch
             {
                 initTouch = touch;
             }
             else if (touch.phase == TouchPhase.Moved)//touch is moving
             {
                 //swiping action
                 float deltax = initTouch.position.x - touch.position.x;
                 //check if swiping in camera and not involve jostick touch;
                 if (RectTransformUtility.RectangleContainsScreenPoint(touchArea, initTouch.position) && RectTransformUtility.RectangleContainsScreenPoint(touchArea, touch.position))
                 {
                     if (deltax > 1f)
                     {
                         deltax = 1f;
                     }
                     else if (deltax < 0f)
                     {
                         deltax = -1f;
                     }
                     // IM TRYING IT HERE
                     if (touch.phase == TouchPhase.Stationary)
                     {
                         freelookCam.m_XAxis.Value += 0f;
                     }
                     else
                     {
                         freelookCam.m_XAxis.Value += deltax * touchSensitivity;
                     }
                 }
             }//THIS CODE WORKS IF I LIFT MY FINGER AND CAMERA STOPS TO MOVE
             else if (touch.phase == TouchPhase.Ended || touch.phase == TouchPhase.Stationary)
             {
                 freelookCam.m_XAxis.Value += 0f;
             }
         }

Please ask if I sound confusing. Sorry.
