it to start the process, goes to Apple's server and authenticates but then when it redirects back to Keycloak, Apple uses a POST request to send back the state and code instead of a GET. It looks like the OIDC provider only supports GET ( https://github.com/keycloak/keycloak/blob/master/services/src/main/java/o... < https://github.com/keycloak/keycloak/blob/master/services/src/main/java/o...>) is there any way around this without creating a custom provider?
