Improving back/home button added to manageCover

JavaScript
26

These two functions need to talk to/connect with each other?

If yes, how do I do that?

function addExitHandler(exitSelector, handler) {
        const exit = document.querySelector(exitSelector);
        exit.addEventListener("click", handler);
    }

    function addPlayer(coverSelector, playerSettings) {
        const clickHandler = createCoverClickHandler(playerSettings);
        manageCover.addCoverHandler(coverSelector, clickHandler);
    }
