How to get count of documents in a query result in mongoose?

To get count of query result:
model.find(queryObj).countDocuments();

To get count of docs in entire collection:
model.estimatedDocumentCount();

try {
      await mongoose.connect(this.mongoDBUrl);
      let collectionName = config.mongoCollectionMap[resource];
      let model = mongoose.model(collectionName);
      if (!queryObj || Object.entries(queryObj).length === 0) {
        return await model.estimatedDocumentCount();
      } else {
        return await model.find(queryObj).countDocuments();
      }
    } catch (err) {
      console.log(err);
      throw err;
    }
