How Can I Add an Action To A Icon on a Graphical Table on Spotfire Using IronPython

I'm trying to create an IronPython script that can remove all the columns from my Graphical Table, add a column with Icons and assign a specific action to this icon whenever it's clicked.

Unfortunately, I still have not found on Spotfire API the part on how to add the action programmatically.

Here is my current core:

from Spotfire.Dxp.Application.Visuals import *
from Spotfire.Dxp.Application.Visuals.Miniatures import *

from System.Drawing import Color

for vis in Document.ActivePageReference.Visuals:
    if vis.Title == 'Selected Period':
        viz = vis.As[GraphicalTable]()

# Remove all columns:
        for c in viz.Columns:
            viz.Columns.Remove(c)

# Add Icon Column
        (status,NewColumn) = viz.Columns.AddNew[IconMiniatureVisualization]()
        NewColumn.AutoConfigure()
        NewColumn.Title = 'Icon'
        NewColumn.IconAxis.Rules.Clear()
        NewColumn.IconAxis.Rules.AddExpressionRule("1=1", Color.FromName("Green"), MarkerShape(MarkerType.Plus))

Does anyone know how to solve this?

Thanks!
