The AWS E-learning course "Creating an IAM Role for AWS Partner-Led Support" describes how to make a specific support role, but doesn't provide the actual template.

This is an advanced way to roll out the role needed, in a multi account structure. If the Partner-Led customer is using AWS ControlTower or AWS LandingZone or some other home baked control mechanism under AWS Organizations, a StackSet is probably the way to go.
