Is there a way to prevent the storyline video player from disappearing?

It's the default Storyline functionality when video controls are enabled. The video controls disappear after a short period of mouse inactivity and reappear when you move the mouse again. The script below prevents this from happening, keeping the video controls visible at all times regardless of mouse activity.

const controls = document.querySelector(".video-animation-container");

controls.classList.remove("controls-hidden");

const observer = new MutationObserver((mutationsList) => {
    for (const mutation of mutationsList) {
        if (
            mutation.type === "attributes" &&
            mutation.attributeName === "class"
        ) {
            if (controls.classList.contains("controls-hidden")) {
                controls.classList.remove("controls-hidden");
            }
        }
    }
});

observer.observe(controls, {
    attributes: true,
    attributeFilter: ["class"]
});
