Here's the deal, you don't need any of this.
I have Rayban Metas and the hardware is great...but the software borders on being unhelpful. If they merely served a dumb camera and bluetooth headset to my phone they'd be an unbelievably good product.
Meta won't do this because they want to capture _everything_ going on, but I don't want to chat with Meta's AI, it is very bad, I want to chat with Gemini or ChatGPT and I can do so with their glasses but I must initiate that on my phone (Meta won't give you wakewords for OpenAI/Google of course).
So my suggestion here would be don't? There is no need for an app store or anything like that, just the thinest software layer you need to make the sunglass hardware work as a dumb bluetooth headset and remote camera for the user's phone.
