Where to find the rules for Abilities for Alola and Galar Pokémon?


Though the main Dex for 1.05 does not include the Alolan and Galar Dex, I have found files for these that are- As far as I am aware, official. However, some Pokémon included in these have abilities that are unique to them and are thus not described in the 1.05 core rulebook. For now, I am (wherever possible) assuming that these are identical to the abilities in the main game with the same name. However, I would like to know the official PTU rulings of these abilities. Where could I find these?
