Tips for Collecting and Enriching Your YouTube Subscriber List

Howdy partners... YouTube Subscriber question for ya! Anyone have luck collecting and enriching their YouTube subscriber list? I'm able to use Influencers.Club to enrich name and email etc. However, it requires the Youtube profile name e.g.: "https://www.youtube.com/@lawtonsolutions" This link is buried in a pop up window. So, grabbing it via the Clay Chrome Extension or Instant Data Scraper hasn't worked for me. I've looked into Phantom Buster and Apify options but I'm not seeing a way to pull the profile name at scale. Anyone managed to figure this out?
