API Solution for Proofreader Notification in Video Translation Automation

I'm currently developing an automation system for video translation and need help replicating a frontend feature using the API.

The Challenge: Notifying Proofreaders Programmatically
In the web frontend, I can share a proofread project with a proofreader via email after its creation. I've successfully implemented the API call to create the proofreads, but I can't figure out how to automatically notify the assigned proofreaders about the new project.

We currently rely on the frontend for this notification, but this process is not scalable with our demands and is becoming unmanageable. We urgently need to achieve this programmatically via the API.

My Question:
Is there a current API solution or a workaround available to programmatically trigger the proofreader notification/sharing of a newly created proofread project?
