Unable to install ca-certificates-mono (or equivalent) on postmarketos / Alpine Linux

Apologies, I don't know much about mono as a whole, though I do know the specific application I have it for and why it's not working, so I hope I'm providing enough info.

I'm running the emulator BizHawk on postmarketos, a derivative of Alpine Linux that also uses the apk package manager. apk offers a mono package, and it's seemingly up to date, but it's just "mono", no mono-complete, mono-dlevel, or anything of the sort. All I know is that BizHawk can't make any connections to the internet because ca-certificates-mono is missing, and I have no way to install it. ca-certificates-bundle can be installed through apk, but that doesn't cover it, sadly. Any way I can install this correctly? Internet connection is the only thing broken in my installation it seems.

Any help is appreciated.
