I am building a scenario where I’d like to create identities using the admin API so that we can also create corresponding user profile records on our own database, keyed by the Ory ID, and also provision initial permissions (using Keto API). What is the correct way to immediately initiate an email verification email, preferably using a one-time-code? The email is not automatically being generated when an identity is created using the admin API and I can only find documentation on how this works for self-service registration flows that are UI-based. (After initial registration, we can use self-service flows for everything else).
