硒:如何看到完整的DOM结构?

Question

我看到过类似的帖子，关于这个问题的解决方案正在使用WebDriverWait。但我仍然得到一个异常错误说选择器不存在。甚至当我在代码末尾打印driver.execute_script("return document.body.innerHTML;"时，完整的DOM也没有显示出来，它看起来与页面源完全一样，但我需要HTML元素的其余部分

from multiprocessing.connection import wait
from ntpath import join
import os
from xml.dom.minidom import Element
from selenium import webdriver
from selenium.webdriver.common.by import By ## Used for grabbing elements by 
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait
import time
os.environ['PATH'] += ";C:seleniumDrivers"
chrome = webdriver.Chrome()
chrome.get("https://jklm.fun/XSNM")
chrome.implicitly_wait(10)
name = chrome.find_element(By.CLASS_NAME, "nickname")
name.clear()
name.send_keys("Mr.Roboto")
btn = chrome.find_element(By.XPATH, '/html/body/div[2]/div[3]/form/div[2]/button')
btn.click()
join_btn = WebDriverWait(chrome, 1000000).until(EC.presence_of_element_located(
chrome.find_element(
By.XPATH, '/html/body/div[2]/div[3]/div[1]/div[1]/button')))
#join_btn = chrome.find_element(By.XPATH, '/html/body/div[2]/div[3]/div[1]/div[1]/button')
#join_btn = chrome.find_element(By.CSS_SELECTOR, 'button[data-text="joinGame"')
join_btn.click()

元素在iframe中。我使用了chrome.switch_to.frame()
