How to Remove Only Certain Playback Speed Options (e.g., 1.75x and 2x) from the Storyline Player?

Hi Haseeb!
Create a trigger that execute this javascript when slide start:

const divs = document.querySelectorAll('div[data-speed="2"], div[data-speed="1.75"]');

// Loop through the found divs to hide their parent li element
divs.forEach(div => {
    const li = div.closest('li');
    if (li) {
        li.style.display = 'none';
    }
});

The speed options (2 and 1.75)  will be hidden.
