Creating new plugin fails (multiple issues)

Open MySQL WB, go to menu Scripting -> Scripting Shell (new window appearing).

Right-click in File Browser to the left -> Add New File (dialog opening).

Select "Python Plugin" -> choose "Generic Plugin" from radio items, leave default names. Then click "Create".

A new tab appears with the default name "myplugin_grt.py" (having an asterisk). Save using Ctrl+S. The new plugin file now appears in the File Browser to the left.

The debugger panel below says:

"Script saved as C:\Users\Kawu\AppData\Roaming\MySQL\Workbench\scripts\myplugin_grt.py
"

The new plugin file has the following contents:

--

# MySQL Workbench Plugin
# <description>
# Written in MySQL Workbench 8.0.36

from wb import *
import grt
#import mforms

ModuleInfo = DefineModule(myplugin, author="Author Name", version="1.0", description="Contains Plugin myplugin")

# This plugin takes no arguments
@ModuleInfo.plugin(myplugin, caption="Caption", description="description", input=[wbinputs.currentModel()], pluginMenu="Utilities")
@ModuleInfo.export(grt.INT)
def myplugin():
# Put plugin contents here
return 0

--

Now click on the lightning button in the toolbar saying "Execute script".

This results in:

"> run
Uncaught exception while executing C:\Users\Kawu\AppData\Roaming\MySQL\Workbench\scripts\myplugin_grt.py:
File "<string>", line 9, in <module>
NameError: name 'myplugin' is not defined"

It's kinda obvious this cannot work. The plugin name must be a string (on line 9 and line 12 respectively).

# MySQL Workbench Plugin
# <description>
# Written in MySQL Workbench 8.0.36

from wb import *
import grt
#import mforms

ModuleInfo = DefineModule("myplugin", author="Author Name", version="1.0", description="Contains Plugin myplugin")

# This plugin takes no arguments
@ModuleInfo.plugin("myplugin", caption="Caption", description="description", input=[wbinputs.currentModel()], pluginMenu="Utilities")
@ModuleInfo.export(grt.INT)
def myplugin():
# Put plugin contents here
return 0

--

Now running this results in:

"> run
Execution finished"

Before return 0 if I enter:

print("Here I am!")

executing the script outputs:

"> run
Execution finished"

Where's the output of my print statement? Why is nothing being output?

BTW, this is really embarassing WB guys...

Regards
Karsten
