Contributions summary:Yiyang primarily contributes to the Okta source connector, focusing on implementing new streams for data extraction. They added streams for GroupMembers, CustomRoles, UserRoleAssignments, GroupRoleAssignments, and Permissions, enabling the retrieval of Okta-related data. Their work involved modifying the source code, adding unit tests, and addressing issues related to data synchronization and schema validation within the Airbyte framework. Furthermore, they added the resource-sets stream, which involved stopping the use of the deprecated method get_updated_state and implementing the state property and state setter instead.
