Overlay Hover to Open Search Results Module

Hi Team!

Is it possible to change the hover function to act as a click, and open the overlay? In other words, a client would like a user to scroll over the overlay button, which would then open the search results module. The client said they would like this implemented to encourage interaction with the overlay. I explained that it is less intuitive and not something I would recommend, but the client is adamant they would prefer this function.

Thank you so much!

Best,
Daniel
