OAuth is Google's preferred way. The user logs in with their normal password, and are then given a token that is used during authentication. Using an app-specific password is only needed for software that doesn't support OAuth. Most modern email programs do support OAuth when accessing Gmail. But lets say you are using an SMTP client written in Delphi/FreePascal, then you might need an app-password unless the client is updated to use OAuth instead.

You don't really need OAuth2 for sending mail via Gmail.
You can just use app passwords.
First enable two factor authentication on your account and create an new App Password here

Use that App Password instead of your normal password and it should work without any modifications.
