Exploring LinkedIn Message Personalization with Clay and HeyReach Integration

In this https://www.clay.com/university/lesson/deep-dive-heyreach-integration-automated-outbound you all say the following "In Clay, you can generate personalized LinkedIn messages for each contact using AI. These messages can then be seamlessly integrated into your HeyReach campaign." How "personalized" can these Linkedin connection invite or Linkedin messages be? Does personalize mean we are simply placing a token in HeyReach that will include (First Name) and (Company) and limited pieces such as that for personalization or is Clay able to customize EACH Linkedin message based on previous research of extensive enrichment data include Linkedin posts, comments, groups liked, etc. It is really important for me to know how personalized these messages can get because the acceptance/reply rates would increase materially if the messages would leverage enrichment data as if they were "draft emails" being prepared. Please advise and thank you.
