I don't know whether kindergarten graduations are popular in America. I don't think so, but my youngest is nearly 30 so who knows what might have changed over the years? My children were home schooled most of the time, so only one of them went to public school kindergarten, and I don't recall any ceremony.

It's a pity you all had to wear masks. Twenty years from now you'll be so sorry you couldn't see that adorable smiling little face. On the other hand, others here on Hive have written about graduation ceremonies being completely canceled because of Covid outbreaks. So at least your little girl was able to participate in hers. Congratulations to her (and to you!) on reaching that milestone!
