How can I implement one interaction on the desktop and for tablet/mobile set the animation to a scroll bar?

This is driving me nuts. I have a cool mouse drag interaction with the Lottie animation that works great for Desktop but tablet and Mobile is a no go. I would like to set a scroll bar for the Lottie in Tablet mode and below so when in a touchscreen, the end user can grab the scroll bar and get the same effect as the mouse drag by playing the animation from start to finish and back with a scroll bar. Is that possible? I have asked in the Animation and interactions several times know to know avail.
Thanks in advance!
