Are there examples of sending messages to the python window or the python console while running plugins?

I am trying to use the following code in %userprofile%\.config\salome\Plugins\salome_plugins.py :

    import salome_kernel

    displayMessage=salome_kernel.GLogger

    def displayLines(context):

        global displayMessage

        dispayMessage.putMessage("Testing Lines ========")

    salome_pluginsmanager.AddFunction('Display Lines', 'Write lines for readability during debugging", displayLines)

It shows up in the salome-mecca 2019 application under Tools > Plugins,

Selecting this plugin does not return any errors, BUT:

I can't see where the message went.

Does anyone know how to see this message and,

Does anyone know the proper way to make a plugin write to either the python console inside Salome or to the Python window that is running the Salome server? 

Thank you.
