Since my plugin only has one QFileDialog importing the whole plugin_utils_light.py library might be a bit overkill.
I put a valid plugin.ico file in the plugin folder and used the following code, but the taskbar icon is still shown.

Spoiler:

def run(bk):   
    # check for supported versions
    if bk.launcher_version() < 20160707:
        print("This plugin requires Sigil 0.9.8 or later.\n\nPlease click OK to close the Plugin Runner window.")
        return -1

    def ensure_windows_taskbar_icon():
        if not iswindows:
            return
        import ctypes
        myappid = 'mycompany.myproduct.subproduct.version'  # arbitrary string
        ctypes.windll.shell32.SetCurrentProcessExplicitAppUserModelID(myappid)

    # Try to import PySide6, then PyQt5
    try:
        from PySide6.QtWidgets import QApplication, QFileDialog
        from PySide6.QtGui import QClipboard, QIcon
    except ImportError:
        try:
            from PyQt5.QtWidgets import QApplication, QFileDialog
            from PyQt5.QtGui import QClipboard, QIcon
        except ImportError:
            raise RuntimeError("No supported GUI framework found (PySide6 or PyQt5).")

    def get_file_path():
        ''' displays a file selection dialog '''
        app = QApplication(sys.argv)
        app.setWindowIcon(QIcon("plugin.ico"))
        ensure_windows_taskbar_icon()
        fpath, _ = QFileDialog.getOpenFileName(
            None,
            "Select LanguageTool Java file",
            "",
            "languagetool-commandline.jar (*.jar)"
        )
        app.quit()

        if not fpath:
            print("Plugin cancelled by user.")
            bk.add_result('info', None, None, 'Plugin cancelled by user.')
            return 0
        else:
            return fpath

What other parts of plugin_utils_light.py will I also need to add to get rid of the icon?
