Where's the Shortcode for the contact form?

I haven’t really written any documentation for the shortcode yet. However, if you use the widget to generate your desired contact form, the shortcode to produce that form will be displayed at the top of the widget; and you can paste that shortcode into a post or Page to generate the contact form. This doesn’t depend on the widget continuing to exist — you can just delete the widget after generating the shortcode, if you wish. (Or keep it around, deactivated, if you want to tweak the form later.)
