How to use the pandasgui.gui.PandasGUI function in pandasgui

def start_gui(**kwargs):
    import sys
    from PyQt5 import QtWidgets
    from pandasgui.gui import PandasGUI

    # Set up QApplication
    app = QtWidgets.QApplication.instance()
    if not app:
        app = QtWidgets.QApplication(sys.argv)

    # Make GUi
    win = PandasGUI(block=True, **kwargs)

    app.exec_()

df_name = "untitled" + str(i + 1)

        for var_name, var_val in callers_local_vars:
            if var_val is df_object:
                df_name = var_name

        dataframes[df_name] = df_object

    # Add the dictionary of positional args to the kwargs
    if any([key in kwargs.keys() for key in dataframes.keys()]):
        logger.warning(
            "Duplicate DataFrame names were provided, duplicates were ignored."
        )
    kwargs = {**kwargs, **dataframes}

    pandas_gui = PandasGUI(**kwargs)

    if store.settings.block:
        pandas_gui.app.exec_()

    return pandas_gui
