Integrating Referral Rewards with Digital Course Access via Zapier

Question on Referral Rewards: Has anybody set up a Referral program so that when a successful milestone is achieved, it triggers an external digital course reward (I'm guessing via Zapier)? Ex. Successfully refers person and the reward automatically grants access/enrolls person into a Thinkific course (Kajabi, Clickfunnels, etc). I have digital courses and trying to keep them under the same umbrella/branding, while still leveraging the Beehiiv referral program. Any advice would be greatly appreciated. Thank you.
