Experimental setting for Symbolic/FullyObs Wrappers

Hi, thanks for the great repository! 

Is there any support or existing experimental settings with an architecture for the ACModel that works with fully observable or symbolic wrapper (observation space: (5,5,3)? 

My experiment setting:
--env "MiniGrid-DoorKey-5x5-v0"
--algo "ppo"

Any help will be greatly appreciated!
