pallet_authorship implementation doesn't work with Aura consensus

Question

I'm trying to get the authors of the blocks using the pallet_authorship but when I inspect the authorship on the polkadot.js app I get none as result.

This is my implementation of the pallet_authorship for the runtime: https://github.com/Datagen-Project/Datagen-Substrate-Grant/blob/744d01400825f7b4ebd8a1ab621739a13e19a09a/fast_blockchain/runtime/src/lib.rs#L302
