How to edit hidden menu from template?

Hello webflowers,

I just started as a non dev on webflow.
Just finding my way around it and watching lots of video’s.
I took a template and it has a Main + second menu.
I cannot seem to find how to edit this second menu.
As ive tried all the guidance I could find at it simply dont want to be visible :frowning:
Does anyone have a similar issue and solved it?
