Activating SAML in Zoho for CRM users

Activating SAML in Zoho for CRM users

Hello,
I'm trying to activate the SAML auth for CRM users to test.
I was able to find how to acitviate SAML ( here : https://help.zoho.com/portal/en/kb/accounts/manage-your-organization/saml/articles/configure-saml-in-zoho-accounts#Prerequisites )
But I can not manage to get the "SSO link" on the CRM login page.
I checked the config of CRM and do not find anything related to this.
Thanks for your insights !
