Authentication is required to obtain an access token (anonymous not allowed)

I try to modify existing example - Tonr2 and Sparklr2. Also I viewed this tutorial based on Spring Boot Spring Boot OAuth2. I try to build application like in Tonr2 example but without first login (on tonr2). I just need one Authentication on Sparklr2 side. I do this:

@Bean
    public OAuth2ProtectedResourceDetails sparklr() {
        AuthorizationCodeResourceDetails details = new AuthorizationCodeResourceDetails();
        details.setId("sparklr/tonr");
        details.setClientId("tonr");
        details.setTokenName("oauth_token");
        details.setClientSecret("secret");
        details.setAccessTokenUri(accessTokenUri);
        details.setUserAuthorizationUri(userAuthorizationUri);
        details.setScope(Arrays.asList("openid"));
        details.setGrantType("client_credentials");
        details.setAuthenticationScheme(AuthenticationScheme.none);
        details.setClientAuthenticationScheme(AuthenticationScheme.none);
        retu details;
    }

But I have Authentication is required to obtain an access token (anonymous not allowed) . I checked this question. Of course, my user is anonymous - I want to login on Sparklr2. Also, I tried different combinations of settings of this bean, but nothing good. How to fix it? How to make it work as I want?
