Question on H1 visa dropbox eligibility requirement

In the article, it’s mentioned as “There have been no US visa refusals in the past. Not just the recent one.”. My F1 visa was rejected once in 2013, then it got approved the 2nd time. In 2021, I got converted to H1 from F1, and my stamping is done in India. Am I eligible for dropbox now, as my F1 was refused once. Please help.
