How to implement this code, anyone suggest please iam trying to message to multiple whatsapp group members in a group

Hi. I need to send whatsapp messages(with and without attachments both) to unsaved contacts. Can you please share how can we do that?
I do not have much knowledge on this. I took code from one repository it was working fine few days ago but now the "Send" is not working. After lot of google search I understood looks like whtasapp might have done some html version changes so the the code which i have is not compatible with it. I tried to get the new Xpath for send button but no luck.

here is the code: I added print messages to trace the failure and I am getting this user defined message: Fail during click on send button.

The commented lines are the new Xpaths I picked from "inspect".

            def send_message_to_unsaved_contact(number,msg,count):
                # Reference : https://faq.whatsapp.com/en/android/26000030/
                print("In send_message_to_unsaved_contact method")
                parms = {'phone': str(number), 'text': str(msg)}
                end = urllib.parse.urlencode(parms)
                final_url = Link + 'send?' + end
                print(final_url)
                driver.get(final_url)
                WebDriverWait(driver, 300).until(EC.presence_of_element_located((By.XPATH, '//div[@title = "Menu"]')))
                print("Page loaded successfully.")
                for retry in range(3):
                    try:
                        sleep(5)
                        wait.until(EC.presence_of_element_located((By.XPATH, '//*[@id="main"]/footer/div[1]/div[3]/button'))).click()
            #          wait.until(EC.presence_of_element_located((By.XPATH, '//*[@id="main"]/footer/div[1]/div[2]/div/div[2]/button'))).click()
                        break
                    except Exception as e:
                        print("Fail during click on send button.")
                        if retry==2:return
                msg_box = driver.find_element_by_xpath('//*[@id="main"]/footer/div[1]/div[2]/div/div[2]')
                for index in range(count-1):
                    msg_box.send_keys(msg)
                    driver.find_element_by_xpath('//*[@id="main"]/footer/div[1]/div[3]/button').click()
            #      driver.find_element_by_xpath('//*[@id="main"]/footer/div[1]/div[2]/div/div[2]/button').click()
                print("Message sent successfully to: ",number)

Thanks in advance for support.

This is slightly improved version of Solomon code, it will keep you logged in.

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait

options = webdriver.ChromeOptions();
options.add_argument('--user-data-dir=./User_Data')
driver = webdriver.Chrome(chrome_options=options)
driver.get('https://web.whatsapp.com/')

name = input('Enter the name of user or group : ')
msg = input('Enter your message : ')
count = int(input('Enter the count : '))
wait = WebDriverWait(driver = driver, timeout = 900)

user = driver.find_element_by_xpath('//span[@title = "{}"]'.format(name))
user.click()

msg_box = driver.find_element_by_class_name('_2S1VP')
#msg += '\n this is a system generated message'

for i in range(count):
        msg_box.send_keys(msg)
        button = driver.find_element_by_class_name('_35EW6')
        button.click()

wait = WebDriverWait(driver = driver, timeout = 600)
driver.close()

i tried this and getting this error, can you help
