How do I keep iPhone 16e Lock Screen lit longer after receiving alerts?

My iPhone 16e sits idle on the desk. Suddenly, the phone lights up with an alert but, before I can even pick up the phone to look at the alert, the screen locks and goes dark again. I already have my lock screen set to a five-minute delay. How else can I keep the screen active for a longer period after an alert is received?

Thanks.
