Module in megamenu

I would like to move the module located under "Layout" (containing an image and a "Contact us" button) to the "Over ons" tab as mega menu.

How do I go about this? I don't see an option for this within the menu items, and the module settings themselves refer to a "module position." I have already updated the image and the text on the button—though not the link, as I still need to create the form itself.
Kind regards
Oswald

Please take a look at the detailed documentation first:
