TypeScript error when property is set on `this` of the Component : Property 'X' does not exist on type Classname

class accountTrack<{},{}> {  constructor() {    this.resetConfig();  }  async init(userMoId:string, accountMoId:string, email:string) {    this._id = uniqueId();    this.userMoId = userMoId;    this.accountMoId = accountMoId;  }}

Looking for the way of proper usage
