Configure SAML auth in Grafana

I’m the user & Implementer of Grafana Enterprise for my client in the Kubernetes Environment bot on Prem & On public Cloud. Currently Grafana integrated with LDAP for valid user authentication& allocating Org ID based Groups to each user after successful Login. If a user is member of multiple LDAP groups (associated with Grafana org-id’s) then user can switch to required groups after Login. I’m trying to migrate LDAP to SAML auth & successfully implemented it. However, i facing issues with seeing listed Org Groups for user & switch after Login if SAML auth used. Its not getting listed. I refer to link Configure SAML authentication in Grafana | Grafana documentation for my configuration. Could you please help?
