SSO Login does not appear in settings

Hello there,
I am trying to configure sso using my organisation g-suit.
I saw that there should be an SSO option on the top level group according to this guide - https://docs.gitlab.com/ee/user/group/saml_sso/
but I don’t see this option under settings tab.
Is this an option open only for paying accounts (we are currently using the free account) ?

Unfortunately I believe this is only available for the silver/premium tiers
