(Wwise) Changing Event State in Unreal Engine 4.26.2

For anyone with WWise-Unreal Engine 4 knowledge:

So I’m trying to create an event in a UE4 project that switches a Wwise state group based on an already created blueprint in the project. This blueprint is working as it should be, but I can’t figure out how to have this state group changed in UE4 by a blueprint.
For more detail, the blueprint switches between 4 different levels based on player action. My Wwise state group has corresponding audio for each level. What I am after doing is having each state switch based on which level the player is at

I’ve got the state group in the engine working manually (where I just switch the state in the blueprint and press “play”).
