Hello, could you contact me? Here is my email: [email protected]. I want to modify a few things, and it will be compensated. Thank you!

Fine!
And a good idea not to use these extra handlers on every page.
Although not quite foolproof: Think of people who are running Ossn in a subdirectory like https://somesite.com/somesubdir/... Your condition would fail then. ;)
Thus, let's recall what you are interested in: Newsfeeds. And nice enough, all newsfeed pages have one thing in common, the ossn-wall-container class. That's why I would replace your condition by

if (document.getElementsByClassName('ossn-wall-container').length) { ....

Just one condition, working not only one /home, but also on group and profile pages

Works fine, thank you!

Made a few adjustments to the code so it only works on /home and it doesn't show the alert

document.addEventListener('DOMContentLoaded', function () {
    if (window.location.pathname === '/home' {
        let refreshDiv = document.createElement('div');
        refreshDiv.className = 'refresh';
        // some add-ons for cleaner placement on Goblue's topbar
        refreshDiv.style.position = 'absolute';
        refreshDiv.style.zIndex = '10';
        refreshDiv.style.top = '-50px';
        //
        document.body.prepend(refreshDiv);

        let startY = 0;
        let isPulling = false;

        document.addEventListener('touchstart', function (e) {
            if (window.scrollY === 0) {
                startY = e.touches[0].clientY;
            }
        });

        document.addEventListener('touchmove', function (e) {
            if (window.scrollY === 0 && e.touches[0].clientY > startY) {
                let diff = e.touches[0].clientY - startY;
                if (diff > 50) {
                    isPulling = true;
                    refreshDiv.style.top = '0';
                } else {
                    refreshDiv.style.top = '-50px';
                    isPulling = false;
                }
            }
        });

        document.addEventListener('touchend', function (e) {
            if (isPulling) {
                setTimeout(function () {
                    refreshDiv.style.top = '-50px';
                    location.reload(); // Trigger a reload
                }, 1000);
            }
            isPulling = false;
        });
    }
});
