Level is not working in editNotification

[smismailalam]

Is there a way to have the notification color change in editNotification because level is not working in editNotification

here is my code for addNotification which is working fine
notify.addNotification({
title: "Message Request",
message: some message,
level: "info",
dismissible: "button",
autoDismiss: 60,
action: null,
});

here is my code for editNotification, level is not working
notify.editNotification(event, {
title: "Accepted",
message: "By another user",
dismissible: "none",
label: "success",
action: null,
level:'success'
});
