Hi, I am a novice and I am trying to port ubtouch for Samsung Galaxy A40. I am following steps for hallium boot.img method and now I am on this page: https://docs.ubports.com/en/latest/porting/build_and_boot/H9_setup_sources.html
I need to add device specific files, but my device does not have official lineage os port. Fortunately there is unofficial lineage os port that I am currently using and the developers behind it seem to release the source code. I think that repos that I need are on this accounts but I do not know which to use because the structure is bit different than in official lineage os account.

Can someone please help me construct manifest file and tell me what to put in /vendor directory? Your help is much appreciated.
