Add a new linked third party app (magento, or any name) to a gmail account and get the password

Given full access to a gmail account, add a third party app to that gmail account, limit it to mail, and get the third party app password from the google mail account. The linked app will be tested from Magento 2.4.4 using the installed smtp extension. This project is NOT about Magento. This project IS about adding the third party app to a Google email account, enabling email relaying.
