I am trying to implement SAML Extension Grant by following the instructions in https://apim.docs.wso2.com/en/latest/Learn/APISecurity/OAuth2/GrantTypes/saml-extension-grant/ but got a blank screen when I tried to configure the service provider:
Sign into the Management Console
Select Service Providers > Add
After I registered the service provider, click Inbound Authentication Configuration > SAML2 Web SSO Configuration.
Click Configure. A blank screen appears.
