Bell Notifications not displaying

Summary:

Hi,
We have written some groovy script to trigger bell notifications following the documentation but nothing is being shown when it is triggered.
And in runtime messages we get:
Triggered a notification with the following message: test message 222 to [300000001229009]

This is from a custom object.

But nothing shows up under the bell, any thoughts?
Cheers
Mark.
