If you desire to display peer reviews that you have conducted, keep in mind that you cannot add them yourself manually. Only a trusted organization that has your permission to do so can add them. Similarly, the peer review section of your ORCID account will not even appear on your personal ORCID record until an organization has added one in the first place. For exact instructions, consider the video below.
Unlike all other facets of your ORCID, peer review is very automated. Reviews of all types, from double-blind to open, are automatically identified together based on a group identifier, usually for the organization that organized the review.
