Unauthorized access with ruby client I am trying to access contacts via the API using the ruby gem in a Ruby on Rails app. Have a test workspace and have created an app in the developer portal in this workspace. Also generated an access token. I am able to create a client object in the rails console. However I get an authentication error when I try and make any calls to the api: [1] pry(main)> intercom = Intercom::Client.new(token: ENV['INTERCOM_TOKEN'], api_version: '2.9')=> #<Intercom::Client:0x0000000130716a48 @api_version="2.9", @base_url="https://api.intercom.io", @handle_rate_limit=false, @rate_limit_details={}, @timeouts={:open_timeout=>30, :read_timeout=>90}, @token="'***************************************">[2] pry(main)> intercom.contacts.find(id: '56f0399fc1f09a1bf6000200')Intercom::AuthenticationError: Unauthorizedfrom /Users/dsingh/.rbenv/versions/2.7.6/lib/ruby/gems/2.7.0/gems/intercom-4.2.1/lib/intercom/request.rb:164:in `raise_errors_on_failure' Is there some other configuration needed for authentication.
