Email template customization for reset password | for Database username/password


My closest related topic here is this one : Sending password change email instead of verification email for a new user

However the Auth0 documention says here :
You cannot make customizations conditional based on the Application ID (client_id).

So the solution seems to me obsolete, and I need to find a new one.

Anyone has found a way to customize the password reset template using a post-register hook?

So that when a user clicks on “reset my password” he receives a normal email to reset his password, and when I manually creates his account, the reset email adds a welcoming paragraph.
