Extracting Return Type of an Effect

Is there a way to extrac the return type of an effect. If i define an effect such that it has a type of

Effect.Effect<{ userId: 1 }, never, never>

Effect.Effect<{ userId: 1 }, never, never>

, is there a defined type that would allow me to extract the

{userId: 1}

{userId: 1}

from that type?
