}

You use the trait and you do $this->fetchAccessTokenForClient($user, $clientId, $tokenId, false) and you get the following result:

array:4 [
  "token_type" => "Bearer"
  "expires_in" => 31532183
  "access_token" => "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImp0aSI6Ijk4MDQxMGY5OTlkODRmYzllOWY4MWEyOTA0NzBlMDc2YjI5YjlmYjNmNTY3NTBmN2QxOGJkZjU0OTg3NzQ5NjE1OTMwMzVhMzBjMzdhODA3In0.eyJh "
  "refresh_token" => "def50200bdae3a7639a12fee90d24ae035907ce71fb585a6c2292ed7dc3421cb9331fd6159bedcc31f16bb909433ef4570dd3ca7dd18bdc315cc464f94d02802db262f7c3fed8c141e2b812415e69a79 "
