Calling table frame layout element from Python Toolbox using ArcPy

I created a Python Toolbox which calculates statisitics about some layers and print a pdf layout.

The layout and table frame elements already exist.

I try to access the table frame elements from my Python script to do some modifcations on fields to show, field order and table frame position.

aprx = arcpy.mp.ArcGISProject("CURRENT")  # my project
m = aprx.listMaps("Map2")[0]  # my map
lyr = m.listLayers("Clip_Reco_Dissolve1")[0]  # source layer for the table frame
lyt = aprx.listLayouts('Tabloid_Paysage_Unique_test')[0]  # my layout
fieldNames = ["Categorie", "COUNT_Categorie"]  # fields to display

elm = lyt.listElements("GRAPHIC_ELEMENT", "Categorie ressource")  # name of the table frame in the layout content

The only way I found in Esri documentation is using last row, but it is not working. I tried again after converting this element to graphic, but it doesn't work either, and anyway I need to manipulate it as table frame to manage fields, before changing its position.

elm = lyt.listElements("GRAPHIC_ELEMENT", "Categorie ressource")
