Alert timeout after firing

Hi there,
we currently use one alert rule that is triggering a webhook for sending a SMS on a mobile phone when a certain value we are getting via influx query is exceeded.
Everything works as expected, however, many SMS are sent in the meantime if the queried measured value is at the threshold value for the alarm for a longer period of time.
Gibt es die Möglichkeit ein Timeout für den Alarm einzustellen, sodass er eine eingestellte Zeit nach dem ersten Auslösen erst einmal nicht mehr feuert?
Thanks for your help!
