[UE4.24] How to trigger an AnimNotify event in Level Blueprints

Hey guys, does anyone know how to trigger an animation notification in Level Blueprints in UE4.24? For instance, I want my Character Mannequin collision presets to set to Ignore when it enters IdleRifle animation. As soon as it enters that animation, it should bypass any WorldDynamic objects - but it seems like it only works in Character Blueprints on Animation Tab, not Level Blueprints. Does anyone know how to pull it off in Level Blueprints?

Use a trigger box and cast it to the level Blueprint
