POST https://YOUR_DOMAIN/dbconnections/change_password only sends verify email

I’m using POST /dbconnections/change_password endpoint to email change the password, but I am just receiving verify email, not change password. Why is that?

My understanding is, when I call this endpoint, it will send verify email first, once verified, then another email with reset password link. Is that correct understanding?

Endpoint: POST /dbconnections/change_password
Request:

{
    "client_id": "{{client_id}}",
    "email": "VALID-EMAIL",
    "connection": "Username-Password-Authentication"
}
