How would you do that not manually? Are tampermonky scripts self modifyable or do you have access to storage?
Try posting this in console and press l on a thumbnail. If you can modify your list, this should work.
if (document.querySelector('.game_cell'))
document.addEventListener('keydown', event => {
if (event.key != 'l') { return; }
setTimeout(() => {
var cell = null;
var hovered = document.querySelector(':hover');
while (true) {
if (!hovered) { return; }
if (hovered.classList.contains('game_cell')) {
cell = hovered;
break;
}
hovered = hovered.querySelector(':hover');
}
if (hovered) {
console.log(hovered.querySelector('.game_title')?.textContent)
console.log(hovered.querySelector('a')?.href)
}
}, 50);
})
