Yes, it was very simple … after hours digging into LOS repos 
And you’re right, there’s no reason to hide my repo. I just forgot to mention it, my bad.
To keep things sorted, I updated [UNOFFICIAL BUILD] Pi/e/ test ROM for Xiaomi Mi MIX 2S - "polaris" with all necessary info
I was too lazy to publish such info for my builds, I’ll add it from now.
