A contact Form Shortcode allows you to add a contact form to any page. Still, to be able to add a form to a specific page, you need to create this form with a Form Builder plugin first. Please read about creating a form in a Contact Form Setup article.
If you have already created one or more forms, you may use a Contact Form Shortcode to add it to your page. For this please select the foem you are aiming to add from a dropdown, add an email address where you want to receive all the messages to, and click "Save".
Need to add a form to a sidebar? See a post about this - Contact Form Widget.
