Dear Node Red community
I'm facing some troubles with the notification node from the node-red-dashboard (V3.6.5).
Briefly explaining the issue - upon detecting a certaing message i'm displaying a notification dialog. If i change the browser tab to another site and for example the flow triggers 10 notifications, then upon returning to the dashboard card i will see a spam of ten notification one after another.
What i would like to achieve is simply to display the last dialog only.
Thanks in advance for any help
