Eufy App vs HomeKit


I’m new here and have a quick question

I have the eufy cam 2c and only use HomeKit, I can see that you can just have HomeKit without the need of the Eufy app, what’s peoples thoughts on this do many of you just use HomeKit without using the Eufy app or a Eufy account

I’m not sure if firmware updates are done over HomeKit for the eufy cams, as that’s the only thing I can see the eufy app doing when just using HomeKit

The only other thing I;ve seen is that there is no 2 way audio with HomeKit tbh they are the first camera I;ve seen without this feature in HomeKit
