Pause button for testimonials module

I would like to add a pause/play button between the arrows on the testimonials module. Some of the wording is quite lengthy and it would be nice to be able to pause the transitions in order to read them fully.

Huge thanks to the helpful post 3 years ago at Testimonials pause ? which documents how to add ‘pause on hover’ to the testimonials module’s frontend.js.php file, which I have added. However this relies on the user a) having a mouse (rather than a finger) and b) knowing to hover in the first place.

I would really like to add a visible pause button in-between the next/previous arrows. Is this possible using a similar edit to the frontend.js.php file?

The “TestimonialsWidget” plugin allows for this feature to pause and play testimonials
