Hi Aravind Vadla,
When using OIDC SSO, you can select the CustomAccessTokenParsing
microflow to get information using Access Token from the IdP. This allows you to assign end-user roles based on the data provided by the IdP. By default there is no access token parsing microflow for Okta IdP, so you need to implement custom access token parsing microflow.
For more details, refer to the documentation here.
