Hi Dulip.
Thank you so much for the feedback and the documentation.
Currently it is not possible to add a COI in the API metadata nor in the UI.
In any case, I have raised this again with the team and shared the documentation that you provided.
The COI subject has been addressed multiple times by our team and we are aware of this. Our main plan and focus right now is to work with COI-specialized platforms and encourage them to use ORCID iDs to make their own work more robust
Thank you again for the feedback.
Best regards
