Hi @Filippo Iacobellis ,
Thanks for reaching out.
It seems you are confused in two features here.
One is Azure AD B2C which is part of Azure AD and one can create B2C tenant using portal.azure.com as mentioned below:
Another is new feature External ID for customers (CIAM) which is different from Azure AD B2C and can be create using entra.microsoft.com portal as mentioned below:
The screenshot of user flow you shared is of B2C tenant, however the link you are accessing is of External ID for customers which has different UI of user flow than B2C.
External ID for customers is new feature for consumers applications. I would recommend you create new external tenant from entra.microsoft.com to get all CIAM functionalities.
Refer to understand difference in Azure AD B2C and External ID for customers: https://video2.skills-academy.com/en-us/entra/external-id/customers/faq-customers
Hope this will help.
Thanks,
Shweta
