Templating, Create Templates !IMPORTANT
Some templates use a specific naming convention.
Those which start with prefix "show_all_" tells the block whether to load assets or not.
Specifically they all do NOT load the carousel animation and that's because by showing all the items at once, a cycling carousel is NOT required.
So please, if you are planning to create your own new template, be aware that you use the name convention ("show_all_") as a prefix to name your custom template, your testimonials will be shown all at once and so the Carousel will NOT be present.
