Official Discord Channels?

Hello everyone,

I am already apart of various discords such as TheSilphRoad and some other unofficial discords. Does anyone know if there is an official PokemonGoHub, Niantic discord channels? Are there any other huge discord servers for developers or people who are data mining the apks?

Also there is a discord channel that PokemonGoHub references alot the PogoDec Discord Channel. What is the invite discord for that?
