Mocking Dependencies in Tests for NotificationApi

 yield* userApi.createUser({
        name
      }).pipe(
        Effect.provide(
          makeTestLayer(UserRepo)({
            getById: () => Effect.succeed(undefined),
          }),
        ),
        // This throws an error 
        // Type 'NotificationRepo' is not assignable to type 'UserApi
        // I need to be able to simply provide a mock of the NotificationApi
        // And ignore any dependencies that it expects
        Effect.provide(
          makeTestLayer(NotificationApi)({
            sendNotification: () => Effect.succeed("ok"),
          }),
        ),
    )
    }),
