If you don't have a controller with an air mouse function or a touchpad, and your X1 device has USB sockets, you could try plugging a normal USB mouse (wireless or wired, shouldn't matter). If you're using a mouse, click and drag the list.
If that doesn't help, might be worth contacting the company that sold you the device and asking if they have any suggestions.
If the USB mouse sorts the problems, but you want to use a more conventional controller, https://www.amazon.com/s?marketplac...9ZCLBW1&merchant=A200LB59ZCLBW1&redirect=true has some you might like to look over.
