Access user BigQuery with com.google.api.services.bigquery or com.google.cloud.bigquery library

Question

I have RESTfull backend application where I need to access users BigQuery tables. In order to do it, I want to use oAuth2, obtain accessToken and then use BQ SDK to manage users BQ tables. In playground I'm able to get an access-token ( https://developers.google.com/oauthplayground ) however I cant see any option to use on backend with SDK. Every authentication option demands p12 or PEM files. Is it any way to use oAuth token in mentioned libraries?

Thanks

As answered by @JonSkeet in the comments, you can have more information about how to use OAuth2.0 with the Java Client Libraries in this documentation page .
