Google rejects OAuth 2 Javax.Mail API with bad credentials

java.lang.RuntimeException: javax.mail.AuthenticationFailedException: 535-5.7.8 Username and Password not accepted. Learn more at 535 5.7.8 https://support.google.com/mail/?p=BadCredentials v7-20020a4a8607000000b0041bdf977c6dsm58061ooh.31 - gsmtp

I am receiving this error when attempting to use javax.mail API to send emails over my GMail account. I attempted to check my settings to verify it allows less secure apps to use my GMail account but the Google website says

To help keep your account secure, from May 30, 2022, ​​Google no longer supports the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password.

Does anyone know where I can find a current guide on how to build hooks to send/receive mail messages with my GMail account that gets around these new requirements?
