Use this interface as an OIDC Federation client. After an end user authenticates and your app receives the AuthenticationData object from the App SDK, initiate the OIDC flow: ```plaintext val config = OidcFederationClient.OidcFederationParams(); config.authFlowUrl = "" config.federationResumeUrl = "" config.tokenUrl = "" config.jwt = Model.sessionData?.get("sessionKey").toString() val client = OidcFederationClient(config, this) client.performCodeGrantFlow().then { result ->    Log.i(TAG, "Code Grant flow completed successfully")    val oidcResult = result as OidcResult    Log.d(TAG, "id_token :" + oidcResult.id_token)    Log.d(TAG, "refresh_token :" + oidcResult.refresh_token) }.error {  exception ->    Log.e(TAG, "OIDC code grant flow failed", exception as Exception) } ``` Class OidcFederationClient contains methods that support the following OIDC flows: - Authorization code grant - Implicit - Token refresh Working example in Tutorial App - MainActivity.kt shows how to initiate OIDC flows.
