Hi there! We actually have a detailed video showing you how to protect your contact forms from spam here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-KhRa7Q1ZoFY.htmlsi=5mbL6Epw94EucoMi :)
We're not sure what you're wanting, the submission would not appear on the front-end of your site normally but if you do set up the form to submit to the front-end of your site you could make it require admin approval.
