Dropbox eligibility in other countries?

It says here that home country requirement to get dropbox stamping done isn’t applicable anymore trbut noone has been able to confirm it. I have a valid stamped H1B visa and I need to get renewal stamping. Am I eligible for dropbox in any other country? Is it written somewhere officially and has someone tried it? If yes, which all countries? I need to know more about step 4 and step 7 in the article - COMPLETE Dropbox Process For 2022 – Eligibility, Document List & H1-B Renewal - Path2USA
