Search engine review stars from product sales

We use your plugin for ecommerce sales on this page https://infinitiworkforce.com/training/purchase-entry-level-driver-training-eldt/ but we do not see any add-ons or ways that we can gain reviews so that the star rating will appear on the search engines to enhance our search results. Do you know of a way that we can achieve gaining a review star rating using your plugin?

Thanks, Jesse
