在自定义页面上显示OpenCart模块的内容

Novice coder here, so please be kind:

I want to duplicate the content from a homepage testimonial module in OpenCart 3.0.2.0 and display it as a single page showing all the testimonials from most recent to oldest.

I have tried duplicating and renaming the module itself (incl. all filenames & contents), but must be missing something as I can't get it to perform as the original module did, let alone customize its output on the front end.

What would be great is creating a module that just takes the original output and then I can format it the way I want through a page template.

Any help would be hugely appreciated, as I'm up against the limits of my understanding now, and the web only provides tantalising glimpses of parts of the answer...TIA

A Screen shot would be nice that explain what you tried

copying information page or shipping module or payment module ?

If your goal is to get a dedicated page to show the module content then this might help you. You can create an empty information page, use its path in creating a new layout and then you can assign the module to that layout. This will show the module on that information page and it will look like a dedicated page for that module.
