I'm currently trying to develop a web extension that opens links from a particular site in a new window

Here is my code:

var links = document.getElementsByTagName("a");
// get links that redirect to medium.com

function getMediumLinks() {
  var mediumLinks = [];
  for (var i = 0; i < links.length; i++) {
    if (links[i].href.indexOf("medium.com") > -1) {
      mediumLinks.push(links[i]);
    }
  }
  return mediumLinks;
}

getMediumLinks().forEach(function(link) {   



    link.addEventListener("click", function() {

       browser.windows.create({
        url: link.href,
        type: "popup",
        width: 800,
        height: 600,
        incognito: true
      });
      

    });
    
    });

But this doesn't seem to happen. Any help is appreciated!.
