Unfortunately, there is no option for the customers to leave reviews right on the website. With the way our Testimonials Slider widget works, you need to manually add the reviews of your customers to the widget. I am so sorry!
We understand that this functionality is really important, and we have such a request in our Wishlist. You can vote for this feature to get notifications about any updates.
As for Google Reviews, customers can leave reviews only on Google by clicking on Write a Review button, but the live reviews option, unfortunately, isn’t available.
Please let me know if this clarifies the situation or if you have any further questions
