What is scope in Amazon Product Advertisement API

Question

I am working on Amazon advertising API. I want to get advertising reports. I am not sure about scope, how I can define scope,

import { HttpClient,ProfileOperation} from '@scaleleap/amazon-advertising-api-sdk'
public static async awsProductAds(store:Store) {
    console.log('testing... ads')
    try {
    const auth = {
      accessToken: store.accessToken,
      clientId: process.env.CLIENT_ID,
      scope: 10000000000 // Use your Profile ID as the value for the management scope
    }
    const httpClient = new HttpClient('https://advertising-api-eu.amazon.com', auth)
    const profileOperation = new ProfileOperation(httpClient);
    const data = profileOperation.listProfiles()
    console.log(data)
    }
    catch (e) {
      console.log('Amazon Ads Report Error : '+e)
    }
  }

Without scope, I am getting this error:

UnauthorizedError: HTTP 401 Unauthorized

Please help how I can get amazon advertising reports with nodejs api-sdk
