Hi @Stevie ,
Thanks for reaching out.
I can understand you are trying to configure SAML IDP in Microsoft Entra External ID for customers but unable to add SAML IDP to user flow.
As Microsoft Entra External ID for customers is currently in preview. It is supporting limited Identity providers.
Currently, only Google and Facebook IDP is supported in Azure AD for customers.
SAML IDP is on roadmap, but no timeline has been confirmed as of now.
Hope this will help.
