How to use the @tsed/core.getValue function in @tsed/core

get(propertyKey: string): T {
    return getValue(propertyKey, this.map);
  }

getRaw(propertyKey: string): any {
    if (["scopes"].includes(propertyKey)) {
      return {
        ...this.default.get(propertyKey),
        ...this.map.get(propertyKey)
      };
    }

    const value = getValue(propertyKey, this.map);

    if (value !== undefined) {
      return value;
    }

    return getValue(propertyKey, this.default);
  }

      return value.replace(/\${([\w.]+)}/gi, (match, key) => getValue(key, this.map));
    }

    if (["scopes"].includes(propertyKey)) {
      return {

    const value = getValue(propertyKey, this.map);

      getValue(propertyKey, {
        get: (key: any) => this._map.get(key)
      })
    );
  }

    return (value: any) => getValue(expression, value);
  }

  }

eval(expression: string, scope: any, clone: boolean = true): any {
    if (isEmpty(expression)) {
      return typeof scope === "object" && clone ? ParseService.clone(scope) : scope;
