Thanks for the review!
The Required fields option in the settings is for field validation, it does not hide the fields in the form.
To hide fields in the form, use the hide option in the shortcode or in the Block/widget options.
For example:
[site_reviews_form hide="email"]
This is further explained in the Shortcodes documentation on the Help & Support page.
I didn’t see the option of Hide Email π
It is just amazing! Amended my review.. π
