Renewal Forever checkbox - New feature in 23A Question

Summary:

I have a few questions regarding the "Renewal Forever" feature:

1. Is there comprehensive documentation available that explains how this feature operates?
2. If we select the checkbox, does it imply that the subscription will never expire?
3. How can we create billing schedules once the subscription's term is reached, allowing us to continue billing without modifying the subscription?
