Technical details:

• twilio-ruby version: 6.6.0
• ruby version: 3.2.2

Start at the Twilio::REST::Client#validation_requests entry point and compare it with the outgoing caller ID example in the linked Twilio documentation. Trace how the v6.6.0 client exposes this resource and determine what change makes that example run without NoMethodError; done means the documented call works with the reported version.
