Error using "find_element" command in python Selenium

Question

I am programming a boot that interacts with a google page (google Meet) for this I am Selenium, but when I use the command find_element in python it gives the following error:

Selenium.common.exceptions.Nosuchelementexception: Message: no such element: Unable to locate element: {"method":"xpath","selector":"/html/body/div[1]/div[3]/div/div[2]/div[3]/div/span/span"}

probably not error the page still not have loaded because I put a 20 seconds Sleep

here is my code:

import os
from datetime import date
from datetime import datetime
from time import sleep
import selenium
from selenium import webdriver

hora = 360
driver = selenium.webdriver.Chrome(r"C:\Users\adelson\Desktop\chromedriver")

def segunda():
    if now.hour == 21:
        os.startfile('link da reunião')
        sleep(20)
        my_button = driver.find_element_by_xpath("/html/body/div[1]/div[3]/div/div[2]/div[3]/div/span/span")
        my_button.click()
        sleep(hora)

while True:

    now = datetime.now()
    data = date(now.year, now.month, now.day)

#segunda
    if data.isoweekday() == 1:
        segunda()
    sleep(120)

Answer 1

Check your xpath if it is correct, this error occurs by not finding the element, which may be caused by the time of the application or the xpath is incorrect.
