Hi there!
Sorry for the inconvenience.
Please use the following code in your custom CSS:
body.ltr .offcanvas-menu .offcanvas-inner .sp-module ul>li.menu-parent>a>.menu-toggler, body.ltr .offcanvas-menu .offcanvas-inner .sp-module ul>li.menu-parent>.menu-separator>.menu-toggler {

}
Note: Path towards custom CSS(Joomla 4): System>Site Templates Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.
