Resolved: Typescript Issue – Typescript dosen’t Infer object properties

const Actions = {
    globalUI: {
        openModal: 'openModal'
    }
}

type Param = keyof typeof Actions;
type T = <T, K extends keyof T>(action: T, key: K) => T[K];
const fn = (param: Param) => {

    const action = mapper(Actions, param);

    return action
}
const mapper:T = (action, name) => {
    return action[name]
}

const action = fn('globalUI');

const Actions = {
    globalUI: {
        openModal: 'openModal'
    },
    LP: {
        addDirectory: 'addDirectory'
    }
}

const action = mapper(Actions, 'globalUI');

action.openModel // works greak

const fn = <S extends Param>(param: S): typeof Actions[S]  => {
    const action = mapper(Actions, param);
    return action
}

const action = fn('globalUI'); 

action.globalUI; // Ok now
