Azure AD B2C auth with username and e-mail

Question

I'm migrating all my users from a legacy IdP to the Azure AD B2C. How can I configure the "Local account" to allow users to login with username OR e-mail?

It seems the Local Account just allows me to configure one of these options but I want to allow users to chose to login with e-mail or username.

Thank you.
