How to use the pandasgui.widgets.find_toolbar.FindThread function in pandasgui

self.current_model = self.current_dataView.model()
        df = self.current_model.df

        # clear matches and selection from last search results
        if self.findThread:
            self.findThread.stop()
        self.search_matches = []
        self.current_dataView.selectionModel().clear()
        self.matches_found_label.setText("Matches Found: 0")
        self.search_selection = None

        if not text:
            return

        # Initialize findThread
        self.findThread = FindThread(df, text, self.match_flags)
        self.findThread.matches.connect(self.update_matches)
        self.findThread.start()
