I have uploaded my Report "Occupational Medicine in Greece. Revised 5 September 2023" on ResearchGate. During the uploading procedure when asked on your website whether I want to have a Doi assigned to it, by Zenodo or Figshare, free of charge, I declined the offer. I changed my mind and now I would like to know whether (and if so, how, exactly), I could have a Doi assigned to it, by Zenodo or Figshare, free of charge, on your website, so that said Report would have a Doi on ResearchGate website. I thank you and hope to hear from you. Dr Theodore Bazas
