Okta.idx password reset

Greetings, dear okta team.

We are in the middle of setting up user self-registration with okta idx (android+ios).
Following the code in the respective repos I presume that I should utilise either reenroll-authenticator or reset-authenticator remediations to initiate a procedure of password reset. Alas, non of the remediations are available after user sign in. Is there a documented approach on best practices how to implement such functionality using okta idx?

Regards, Roman.
