No clear documentation of "Origin: Advertisement" in Route Table routes

[jalilm]

Describe the issue

When issuing describe-route-tables, as part of the Routes of a specific table, I'm receiving the following rule:

{
  "DestinationCidrBlock": "192.168.100.0/24",
  "Origin": "Advertisement",
  "State": "active"
}

The "Advertisement" origin is not part of built-in RouteOrigin option, there is no clear documentation of when it is used. Reading around the internet suggests it is due to BGP Advertisement of routes. Which seems plausible given the name and lack of "target" in the rule. If this is correct, is it possible to document it and provide into on where the advertising BGP "router" id is stored, or how it can be retrieved?
