Hello, the TextActor was not supported in VtkLocalView, it's also cannot be serialized, Is it planned to be added in vtklocal?

class name：vtkOpenGLTextActor

code example

from trame.app import get_server
from trame.ui.vuetify3 import SinglePageLayout
from trame.widgets import vuetify3

from vtkmodules.vtkRenderingCore import (
    vtkActor,
    vtkPolyDataMapper,
    vtkRenderer,
    vtkRenderWindow,
    vtkRenderWindowInteractor,
)

from vtkmodules.vtkCommonColor import vtkNamedColors

from vtkmodules.vtkFiltersCore import vtkTriangleFilter
from vtkmodules.vtkFiltersSources import vtkPlaneSource
from vtkmodules.vtkRenderingCore import (
    vtkActor,
    vtkPolyDataMapper,
    vtkRenderWindow,
    vtkRenderWindowInteractor,
    vtkRenderer,
    vtkTextActor
)

from trame_vtklocal.widgets import vtklocal

def create_text_actor(myText):
    colors = vtkNamedColors()
    txt = vtkTextActor()
    txt.SetInput(myText)
    txtprop = txt.GetTextProperty()
    txtprop.SetFontFamilyToArial()
    txtprop.BoldOn()
    txtprop.SetFontSize(36)
    txtprop.ShadowOn()
    txtprop.SetShadowOffset(4, 4)
    txtprop.SetColor(colors.GetColor3d('Cornsilk'))
    txt.SetDisplayPosition(20, 30)
    return txt
    
def setup_vtk():

    colors = vtkNamedColors()

    plane_source = vtkPlaneSource()
    plane_source.Update()

    triangle_filter = vtkTriangleFilter()
    triangle_filter.SetInputConnection(plane_source.GetOutputPort())
    triangle_filter.Update()

    mapper = vtkPolyDataMapper()
    mapper.SetInputConnection(triangle_filter.GetOutputPort())

    actor = vtkActor()
    actor.GetProperty().SetColor(colors.GetColor3d('SeaGreen'))
    actor.SetMapper(mapper)

    renderer = vtkRenderer()
    ren_win = vtkRenderWindow()
    ren_win.AddRenderer(renderer)
    ren_win.SetWindowName('CellPicking')
    iren = vtkRenderWindowInteractor()
    iren.SetRenderWindow(ren_win)
    # add text actor
    renderer.AddActor(create_text_actor("hello trame"))
    
    renderer.AddActor(actor)
    renderer.ResetCamera()
    renderer.SetBackground(colors.GetColor3d('PaleTurquoise'))
