DOC: Visualization report is incorrect

[SMoraisAnsys]

Currently the documentation on visualization report as an error. The following code is not working:

    from ansys.aedt.core import Hfss
    from ansys.aedt.core.visualization.report.field import Fields

    app = Hfss(specified_version="2024.2",
               non_graphical=False,
               new_desktop_session=False
               )
    test_points = [["0mm", "0mm", "0mm"], ["100mm", "20mm", "0mm"],
                   ["71mm", "71mm", "0mm"], ["0mm", "100mm", "0mm"]]
    p1 = app.modeler.create_polyline(test_points)
    setup = app.create_setup()

    report = Fields(app=app, report_category="Fields",
                    setup_name=setup.name + " : LastAdaptive",
                    expressions="Mag_E")
    report.polyline = p1.name
    report.create()

After looking into it the solution can be to simply change app=app.post or to manually create the post app, e.g.

from ansys.aedt.core.visualization.post import post_processor
post_app = post_processor(app)
report = Fields(app=app, report_category="Fields",
               setup_name=setup.name + " : LastAdaptive",
               expressions="Mag_E")

Since the first approach seems more elegant, I'll propose the associated changes.
