Send messages to display in Seam notch

I really like how the notch expands for some messages, or when a file is being dragged. It would be fantastic, if I could trigger the display of messages or notifications from other applications (e.g. own applications). This could happen via NSDistributedNotificationCenter, Apple Events / AppleScript or custom URL scheme lie

NSWorkspace.shared.open(URL(string: "seam://action?message=”Display this message.")!).
