aaronlbpeterman the "official" way is through GitHub. Although I've never seen anyone request an update there (GitHub doesn't receive much attention in general, I want to look for ways to put it more on eyes). Maybe it's because that I keep every extension up-to-date once in a while (approx. every week).
You can just ping me anywhere, even on Discord, write me a mail or send a letter - I'll get the message. As for appropriate way, then that's GitHub, but I think that extension update isn't that big deal to be requested in an issue. A simple message will do the trick
