Recommend to switch on. After the integration has been performed, any new records in your ORCID Works section will automatically be pulled to IRR (Figshare) as draft metadata records in your My data area, so that you do not have to create metadata records manually.
Note: It is recommended that you use the Search & link wizard to add works to your ORCID record, i.e. importing publication data from other systems/databases (e.g. Crossref, Scopus). This will allow you to populate more complete citation information (e.g. collaborators field) into your ORCID Works.
