How do I set up a trigger in Azure DevOps and map changes to a task's progress field in Team Gantt?

I’m trying to create a Zap that updates a task’s progress in Team Gantt based on the 'roll up by task' percentage from Azure DevOps. Specifically, I want the Zap to trigger whenever the 'roll up by task' percentage for a work item in Azure DevOps changes, and then map this percentage to update the corresponding task progress in Team Gantt.

Here’s what I need help with:

1. Trigger Setup: How do I configure a trigger in Azure DevOps to capture changes to the 'roll up by task' percentage?
2. Action Setup: What’s the best way to map this percentage to the progress field of a task in Team Gantt?
