Are SynoCommunity packages included in HyperBackup (or elsewhere for backup)?

Recently learned about the SynoCommunity packages, but I saw this comment for a package that HyperBackup might not recognize a package and thus not back it up. However, it was unclear if it was for the particular package, or if this is a shortcoming of the SynoCommunity packages—since it's a third-party thing, maybe it applies to all SynoCommunity packages.

Does anyone know if installing a package via SynoCommunity can be backed up through HyperBackup (or another way)? Thanks.
