	export function cancelPermissionPrompt(permissions) {
	// we cannot actually really close the permission prompt, see:
	// https://discourse.mozilla.org/t/can-browser-extension-permission-requests-be-cancelled/44734?u=rugkx
	const thisPermission = getInternalPermissionData(permissions);
	thisPermission.messageBoxes.forEach(hideMessageBox);
	}
