How to make properties (getters/setter) on TypeScript classes enumerable?

I need my getters & setters to be enumerable, however, TypeScript emits ES6 class syntax, and class properties are not enumerable in javascript.

Is there a typescript config or something else I can do that forces class properties to be emitted as Object.defineProperty() with enumerable: true?

Edit: It looks like this can be achieved with property decorators, how might that be done in this case?

Example:

class User {
 public roles: string[];
 
 get isAdmin() {
    return this.roles.some((role) => role === 'admin');
 }
}

// This should be `true` not `false`
console.log(Object.keys(new User()).includes("isAdmin"))

If a User instance gets passed into a Vuex store for instance, the non-enumerable members are dropped, and isAdmin no longer exists.
