How to get authorize code to dismiss login page with oauth2 wso2 identity server

Question

I'm using WSO2 Identity with structure below:
Client -> My Web Application (/my-app) -> WSO2-is (this is private zone)
I created service provider on WSO2-is and config all of the necessary information (use OAuth2).
Client access /my-app/login?client-id=<CLIENT_ID>&redirect_uri=<REDIRECT_URI>&response_type=code...
Then will be submit username + password. My application catch the submit request, then send the request to WSO2-is endpoint: https://localhost:9443/oauth2/authorize.
How to init request with parameters to get authorization code directly?
I was referenced wso2-is documentation. The authorization code will be insert into a table IDN_OAUTH2_AUTHORIZATION_CODE. With the authorization code, i gonna get access token from https://localhost:9443/oauth2/token endpoint.
I can get access token directly with oauth2/token endpoint by grant_type is password, but I'm only want to get access token by workflow description above

Use the BasicAuthRequestPathAuthenticator from the Local Authenticator section to skip the login page as below. You also might want to skip the login consent as well.
