Console app not showing info and debug logs

I have a Swift 3 Cocoa application that uses Apple's Unified Logging, like this: -

    import os

    class MyClass
    {
        @available(OSX 10.12, *)
        static let scribe = OSLog(subsystem: "com.mycompany.myapp", category: "myapp")

        func SomeFunction(){
  
            if #available(OSX 10.12, *){
                os_log("Test Error Message", log: MyClass.scribe, type: .error)
            }

            if #available(OSX 10.12, *){
                os_log("Test Info Message", log: MyClass.scribe, type: .info)
            }

            if #available(OSX 10.12, *){
                os_log("Test Debug Message", log: MyClass.scribe, type: .debug)
            }
        }
    }

Within the Console application, both

Include Info Messages

Include Debug Messages

When

os_log

error

Using Terminal, with the command, all message types are visible in the Terminal output: -

sudo log stream --level debug

I've tried running the Console app as root, via sudo from the command line and the same issue occurs; no debug or info messages can be seen, even though they're set to being turned on under the Action menu.

Setting system-wide logging to be debug, has no effect on the Console application output:

sudo log config --mode level:debug

Please can someone tell me what I'm missing and how can I view debug and info messages in the Console application?
