Plugin Disables Link Feature in Editor

Hi,
when your sticky-buttons-plugin is enabled in wordpress 5.6 or higher – the insert/edit link feature is no longer working in classic editor, nor in gutenberg or wp bakery. it still works in classic mode using the text – link feature – but in visual mode the link button has no function. disabling the plugin solves the issue
