I want to change the add event url to go

I want to change the add event url to go to ibsregister.com/add-event/

Instead of

ibsregister.com/members/baobab/my-events/edit-event/

I have tried adding

function replace_add_event() {
		remove_action( 'eab-events-my_events-set_up_navigation', array(Eab_Events_FrontPageEditing(), 'my_events_add_event') );

		function new_add_event () {
			global $bp;
			bp_core_new_subnav_item(array(
				'name' => __('Add Event', Eab_EventsHub::TEXT_DOMAIN),
				'slug' => 'add-event',
				'parent_url' => trailingslashit(trailingslashit($bp->displayed_user->domain)),
				'parent_slug' => '',
				'screen_function' => 'bind_bp_add_event_page',
			));
		}

		add_action( 'eab-events-my_events-set_up_navigation', array(Eab_Events_FrontPageEditing(), 'new_add_event'));	

	}

	add_action( 'eab-events-my_events-set_up_navigation', 'replace_add_event' );

To function.php but that doesn't work. I just get a blank screen

Thanks
