Greasy Fork

Hi, I am new to userscripts, how can I click on this button (there is only 1 per webpage, not more for info) on this webpage https://www.leboncoin.fr/jeux_video/2540607208.htm

I am using this scripts:
"
const buttonElem = [...document.querySelectorAll('button')].find(x => x.innerText.includes('Voir plus'));
console.log(buttonElem);
buttonElem.click();
"

The button is properly found (1st line), but I don't understand why the click does not work. Regards

setTimeout(() => {
  [...document.querySelectorAll('button')].find(x => x.innerText.includes('Voir plus')).click();
}, 3000);

Thank you, I have just tested it works great.
I had 2 mistakes:
- @run-at was document-load
- I did not used a timeout
