It appears that the official chrome webstore extension by Rob W is outdated. It was last updated in 2019. 

console.log();
  console.log("### Creating reference images");
  let forceNoChrome = false;
  const args = ["test.js", "--masterMode"];
  if (bot) {
    const os = process.env.OS;
    if (/windows/i.test(os)) {
      
      
      forceNoChrome = true;
    }
    args.push("--noPrompts", "--strictVerify");
  }
