How well do Google Maps and WhatsApp work on the latest versions of HarmonyOS?

I assume it requires some mind of Android compatibility layer that won't pass Play Integrity checks..

Does Huawei provide an Android virtual machine with Google frameworks built in? When I was traveling in Japan, I used Google Maps, and for daily use, Chrome and 1Password all worked fine.

In my daily use, only three apps run in the virtual machine: 1Password, Steam, and Chrome. They all run normally, but they're a bit laggy.
