These are notifications from agent.js
JetBrains' implementation runs it at the start of the editor, after initialization. Seems that it returns messages about Copilot state.
method = "window/showMessageRequest"
Type:
{
type: "int", // MessageType
message: "string",
actions: [{ title: 'String' }] // not very investigated that
}MessageType { Error = 1, Warning = 2, Info = 3, Log = 4 }
They are exist in JetBrains implementation, but I didn't research them much.
"window/logMessage" "LogMessage"
"statusNotification" (exist in Vim https://github.com/github/copilot.vim/blob/1358e8e45ecedc53daf971924a0541ddf6224faf/autoload/copilot.vim#L63) probably
{
status: "",
message: ""
}
