ESPHome git checkout location on HAOS

Can anyone tell me where the git clone / checkout is done when building an updated firmware for a ESPHome device when ESPHome is installed as an Add On in HAOS?

Just hit install?! The idea of the Add On is that you don’t need to care about got, docker and what not!

If hitting install worked, I wouldn’t be asking this question. I’m trying to debug a failed git submodule dependency that I’ve already created an issue for. I want to get into the checkout to see if I can better diagnose the issue or propose a fix.
