How to customize Supplier portal emails?

Summary: We are needing to update the Welcome email, password reset email, and password reset confirmation email to include the link to the supplier portal log in screen. I found another customer connect question that basically answered this (https://community.oracle.com/customerconnect/discussion/495233/how-to-include-username-in-new-supplier-user-account-email) but the official documentation is not showing up after opening the link on the post (https://docs.oracle.com/en/cloud/saas/applications-common/19b/faser/managing-implementation-users.html#FASER2253505)
