Spectator Spawn - Where is the "SpectatorPawnMovementComponent"

Im using a Spectator spawn in my scene to fly around.

I want to change what the “Spacebar” input does.

From Unreal Docs " The movement for the SpectatorPawn class is handled in the SpectatorPawnMovementComponent"

Where can i access this? (I cant C++, just Blueprint - if that makes a difference)

Could be simple…
