Add "Create User" to Zapier (helpful for Thrivecart users)

Had a great discussion in The Hearth community around how to create members in Heartbeat when a user purchase several funnel offers from a Thrivecart checkout (bump, upsell etc.) See discussion here: (https://app.heartbeat.chat/community/t/automation%20help/f04f4d8d-7737-4142-918c-6bbfeaaa23c9)

However, while there seems to be an easy fix with Pabbly, there isn't one with Thrivecart. In Zapier, you have to set up separate trigger zaps for purchases, bumps, upsells and downsells. If someone buys let's say a PRODUCT + BUMP -> that's two separate zaps. Depending on which invite link they choose to click on will only give them access to that product.

My request is to have this same "Create User" action added to Zapier so that we can create a simplified automation that gives our members correct access.
