How to create PublicClientApplicationConfiguration dynamicly?

[NLLAPPS]

Hi, I am trying to build PublicClientApplicationConfiguration in Java rather than using json file.
My json config is
` {
"authorities": [
{
"type": "AAD",
"audience": {
"type": "AzureADandPersonalMicrosoftAccount"
},
"default": true
}
],
"account_mode": "SINGLE",
"authorization_user_agent": "WEBVIEW",
"multiple_clouds_supported": true,
"client_id": "XXXXX",
"redirect_uri" : "msauth://XXXXX",
"broker_redirect_uri_registered": true,

"http": {
"connect_timeout": 10000,
"read_timeout": 30000
}
}`

So far I have below but cannot seem to figure out how to set "account_mode": "SINGLE" and "authorization_user_agent": "WEBVIEW" in Java. Where/How would I set those?

            PublicClientApplicationConfiguration publicClientApplicationConfiguration = new PublicClientApplicationConfiguration();

            publicClientApplicationConfiguration.setClientId("XXXXX");
            publicClientApplicationConfiguration.setRedirectUri("msauth://XXXXX");
            publicClientApplicationConfiguration.getHttpConfiguration().setConnectTimeout(10000); 
            publicClientApplicationConfiguration.getHttpConfiguration().setReadTimeout(30000);  
            publicClientApplicationConfiguration.setPowerOptCheckEnabled(false); //Disable so that we can work in background 

            AzureActiveDirectoryAuthority azureActiveDirectoryAuthority = new AzureActiveDirectoryAuthority(new AllAccounts());
            azureActiveDirectoryAuthority.setDefault(true);
            azureActiveDirectoryAuthority.setMultipleCloudsSupported(true);


            publicClientApplicationConfiguration.getAuthorities().add(azureActiveDirectoryAuthority);
