Mobile search not working

On mobile and tablet view, I can’t see the search button in my header, even in the dropdown hamburger. On my desktop, it’s the farthest right button on the header, just after the account button. But on mobile/tablet, the account button is the last one and the search button doesn’t show up anymore.

I have Elementor and Marra Core Theme
I tried to read past threads on this, but I didn’t understand the responses, e.g. where to find the things stated that I should check.
