Question PreDownload Remote Addressables Group outside of Unity

Hi,
I'm building application where Unity player intergrated into native app(iOS/Android)

I want to download remote addressables data before Unity player actually launched.

I spend some time to discover how Unity stores remote addressables on device.

Path prefix formed by
[AssetBundleRequestOptions.BundleName]/[AssetBundleRequestOptions.Hash]

So by knowing this, I could simulate Addressable Caching without Unity,
However, I still need to manually build mapping for those [bundle hash]: [addressable_group hash]
but one thing I don't know is __info
I can't find in code where and how it's generated and what actually inside.
(Attached sample of __info file)




So my question is does anybody tried this before?
Am I on the right way, is there is any better way to do this?
What is __info file and how to manually create it?

 

Maybe the proper question then is "How to change Local Load Path from StreamingAssets to Application.persistentDataPath"
