Behaviour of PATCH /api/v2/users/:id - updating with exactly the same email

Hi,

What is the behaviour of PATCH /api/v2/users/:id

Scenario1: when I try to update with exactly the same email. i.e userA has email as test@gmail.com and I send a patch request with test@gmail.com (no changes at all, exact same email as earlier). Will the Auth0 update the email and email_verified flag? or no changes are done in this case? What is the response code received?

Scenario2: what happens when try to update the email with an email in use for another user , what is the error code returned in this case? also impact on email_verified if any due to this?
