Is it possible to remove attachment?

i can remove full information from title message and this attachment to notification will be as on the second screenshot
but I can’t find any information on how to remove this attachment to the message where you can see “Grafana v10.1.1”
( i just need text strings without any attachments/blanks)

Can anyone paste here link on documentation or maybe someone saw similar problem
or maybe you have ready to use example?)
