Generic factory class with Node.js TypeScript MongoDB Driver generic Collection

Hi guys, I am trying to build a generic Class (in TypeScript) that will help me to build factorized Models in a reusable fashion. The Class receives a generic type, called T. Then the class creates a new generic MongoDB Collection using the Class’s generic prop that was passed to the Collection generic type, as follow:

class Model<T extends Document> {
  collection: Collection<T>
  constructor(private colName: string) {
    // suppose this.client is defined, removed in sake of simplicity
    this.collection = this.client.mongo.db().collection<T>(colName)
  }

  findById(id: string) {
    return this.collection.findOne({ _id: id }) // will get typescript error.
  }
}

No matter what you will write in the .findOne method. It will always get a Type error from TypeScript.
This is probably since TypeScript cannot tell what are the actual properties of the Filter in the .findOne prop - since they are unknown generic (in our case, just T).

Should I use // @ts-ignore in this case? Or that should be a proper work around to implement this idea?
