pythonスクレイピング　seleniumのエラーについて

python初心者です
seleniumを使いTOKENLINKというサイトのマーケットにあるアイテムの名前と価格を取得しリストアップしようとしてました。
ですが、実行してみるとエラーが起きてしまいます。

エラーの理由と解決方法を教えてください。

（ソースコードmain.py）

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

options = webdriver.ChromeOptions()
options.add_argument("--headless")

browser = webdriver.Chrome(ChromeDriverManager().install())

url = "https://www.tokenlink.io/market.html"
browser.get(url)

items = browser.find_element('item-name')
print(items[0].text)

（エラーコード）
