Eufy security alerts on phone

I have a Eufy Homebase system with cameras and door sensors synced up. At the moment, when the door sensor is triggered, I receive an alert on my phone, with a brief sound. However, I would like to set it so that when the door sensor is triggered, my phone sounds an alarm until I stop it (this will be useful for me if I am, for example, staying away from home and someone triggers the door sensor in the middle on the night). Any ideas please…?
