Login to Google with Selenium via stackoverflow error - python-3.x

Question

I am trying to create a script that will login to my google slide presentations and update them. In order to do this with Selenium it appears I have to login each time which causes the 'This browser or app may not be secure' error page, shown below.
I researched online that you should be able to work around this by logging in through stackoverflow or another site that uses 'log in with google'. However my below attempt seems to still provide the same results. Following up on this, I wasn't able to find out if this is still doable or if this approach no longer works.
Could someone confirm if my approach is outdated or if there is something I've failed to grasp from my approach? Sorry if I've missed something basic, I've just started writing Python so I'm deep in the learning curve stage.
I'm using Ubuntu 20.04 if that's of any use.
Code
#!/usr/bin/env python3
import webbrowser

Answer 1

This is because automation testing frameworks are disabled by Google for security reasons
However, there are a few things you can do:
The easiest way: Open browser controlled by selenium, open stack overflow and perform authorisation manually. When you next run the script, it will log you in automatically.
Add arguments to the script that block web security:
from selenium.webdriver.firefox.options import Options
options = FirefoxOptions()
options.add_argument('--disable-web-security')
options.add_argument('--user-data-dir')
options.add_argument('--allow-running-insecure-content')
You can also do this in the terminal.
Login to stackoverflow with your google account, once logged in go to your email.
driver.get("https://accounts.google.com/signin/oauth/identifier?client_id=717762328687-iludtf96g1hinl76e4lc1b9a82g457nn."
+ "apps.googleusercontent.com&scope=profile%20email&redirect_uri=https%3A%2F%2Fstackauth"
+ ".com.com%2Fauth%2Foauth2%2Fgoogle&state=%7B%22sid%22%3A1%2C%22st%22%3A%2259%3A3%3Abbc%2C16%3Af343579f103b7116%2C10%3A1611315201%2C16%3A360adcabd84812cf%2Cc1c668aab33e5327311ff2c3a0cb356918a99d0d6cb65a0da11008340199a802%22%2C%22cdl%22%3Anull%2C%22cid%22%3A%22717762328687-iludtf96g1hinl76e4lc1b9a82g457nn.apps.googleusercontent.com%22%2C%22k%22%3A%22Google%22%2C%22ses%22%3A%225b28397546b247c7994c2d3cd480cc31%22%7D&response_type=code&flowName=GeneralOAuthFlow");
driver.find_element_by_id("identifierId")\ #entering username
.send_keys("email#gmail.com")
sleep(2)
driver.find_element_by_id("identifierNext").click() #clicking next
driver.find_element_by_name("password")\ #entering password
.send_keys("password")
driver.find_element_by_id("passwordNext").click()#clicking next

driver.get("https://mail.google.com/mail/u/0/#inbox") #going to email inbox
