Remove class of a div when clicking on another in vanilla JS

(Sorry for my English, it’s not my native language)

I created a function that widens a wrapper containing a visible small element and display an invisible element (map). If I click on another wrapper, the function works as well, but I would like to cancel the effect on the first wrapper.

Can you help me?

wrapper.forEach((wrapperElement)=> {
    let mapElement = wrapperElement.querySelector(".map");

    wrapperElement.addEventListener('click', function reset(){ 
        mapElement.classList.toggle('show');
        wrapperElement.classList.toggle('focus');

    });
});

I think I should attribute isWiden = true to the first wrapper, and the function would test it before targeting the second wrapper. But I’m struggling to do that.
