Mobile Mega Menu – Expand Submenu on Label Tap

Hello,
I have a question regarding the mobile version of the Mega Menu.
Is it possible to make the "Oferta" menu item expand the submenu when tapping on the text itself (not only the arrow)?

Currently, on mobile devices, tapping the word "Oferta" opens a page, while the submenu only opens when tapping the arrow icon. I do not want to create or link to any page for "Oferta" — I just want it to expand the submenu when the label is tapped.

I’ve attached a screenshot and here is the link to the page:

Thank you in advance for your help!
