Okta SAML Integration - How to import groups?

I’m integrating with an Okta IDP but when I try to load the groups by ticking " Import user groups from the identity provider" from this identity provider, I see that “Organization assignment must be managed in Control panel to import group”.

Where is that setting ? How can I import group from this identity provider ?

You need to go in the “Authentication > Okta” page in Control Panel and click on “Configure” button in “Organization assignment”.
From there, you can “Import user groups from the identity provider”.
