Kotlin create email client (javamail, Google OAUTH, kotlin) - AUTHENTICATIONFAILED invalid credentials (failure) - kotlin

Question

I'm trying to develop a small android email client in kotlin.
I use javanais api and google OAUTH but I got the following message.
-----TEST START-----
-----TEST BP1-----
-----TEST BP2-----
ERROR:javax.mail.AuthenticationFailedException: [AUTHENTICATIONFAILED] Invalid credentials (Failure)
ERROR MESSAGE : [AUTHENTICATIONFAILED] Invalid credentials (Failure)
ERROR MESSAGE : kotlin.Unit
The retrieval of the google oauth token works well but not the passing it to javanais api.
