ELM LM_NOTIFY Application Engine program interrelated to the Roster component

In PeopleSoft Enterprise Learning Management (ELM) 9.2, what is the function of the LM_NOTIFY Application Engine program? Does LM_NOTIFY create new notification records or read existing notification requests from tables such as PS_PT_WF_NOTFT_TBL or any other ELM-specific notification tables?

How is LM_NOTIFY App engine linked to the Roster component (LM_LC_ROSTER.GBL), where instructors or administrators record attendance, scores, and grades?When a learner’s attendance is updated, score is entered, or grade is posted, how do these actions generate notification requests that are later processed by LM_NOTIFY?

Which records, components, or PeopleCode events (such as SavePostChange or Workflow PeopleCode) are responsible for inserting notification requests related to these roster updates? Is there any reference documentation, record flow diagram, or delivered example process available that shows how notifications flow from roster activity to notification delivery in ELM 9.2?
