From Laura:

We need to update this to use the process/interface used in https://access.redhat.com/documentation/en-us/red_hat_openshift_data_science/1/html/managing_users_and_user_resources/adding-users-for-openshift-data-science_useradd#adding-users-to-specialized-openshift-data-science-user-groups_useradd

It looks like the reported section and the following one should be updated: https://access.redhat.com/documentation/en-us/red_hat_openshift_data_science/1/html/managing_users_and_user_resources/adding-users-for-openshift-data-science_useradd#adding-existing-user-groups-from-an-identity-provider-to-openshift-data-science_useradd
