When ORCID plugin enabled, is it mandatory to authorize on the user registration process?

Hi.

I get a little confused. OJS ver. 3.1.2-4
If I activated ORCID and never click the button from ORCID authorized button and fill up all the information on the user registration and click submit to register. This redirects me on the same registration page without any information about error or nothing just an empty registration form and off course the registration process is failed.

But if I authorized the ORCID and complete all the input on the registration page it is working well.

My question:
When ORCID plugin enabled, is it mandatory to authorize the user registration process to continue with the process ?
