How to open Mobile Menu dropdown?

I can’t figure out how to open and edit the mobile menu dropdown. Other dropdowns are usually toggled on/off under the “settings” tab but it doesn’t appear there at all for the template I’m using. How can I open and edit it?

Here is my site Read-Only: Webflow - Jose Gonzalez-Campelo Portfolio

FYI: When using a template hit up the template developer first before posting in the forum. Cheers.
