Need help identifying the generic client side type of procedures

Hi! I think my question is better explained by what I'm trying to achive than anything else: I like to create a function called "subscribe" that can receive any subscription procedure and subscribe to it: e.g (sudo code):

const onRandomNumberRecived = (n: number) => {}
subscribe(trpc.randomNumber, onRandomNumberRecived);

const onRandomNumberRecived = (n: number) => {}
subscribe(trpc.randomNumber, onRandomNumberRecived);

Below is the infered type, but I'm pretty sure there is an generic type to represent such a thing "somewhere":

(property) randomNumber: {
    subscribe: SubscriptionResolver<BuildProcedure<"subscription", {
        _config: RootConfig<{
            ctx: {};
            meta: object;
            errorShape: DefaultErrorShape;
            transformer: DefaultDataTransformer;
        }>;
        _ctx_out: {};
        _input_in: typeof unsetMarker;
        _input_out: typeof unsetMarker;
        _output_in: typeof unsetMarker;
        _output_out: typeof unsetMarker;
        _meta: object;
    }, Observable<{randomNumber: number;}, unknown>>>;

(property) randomNumber: {
    subscribe: SubscriptionResolver<BuildProcedure<"subscription", {
        _config: RootConfig<{
            ctx: {};
            meta: object;
            errorShape: DefaultErrorShape;
            transformer: DefaultDataTransformer;
        }>;
        _ctx_out: {};
        _input_in: typeof unsetMarker;
        _input_out: typeof unsetMarker;
        _output_in: typeof unsetMarker;
        _output_out: typeof unsetMarker;
        _meta: object;
    }, Observable<{randomNumber: number;}, unknown>>>;

I've been digging through the source code, but so far I had no luck reproducing it. Have anyone attempted something similar?
