How to use querySelectorAll() to get an elemnt by the value of its property?

Given some elements like <section style="order: 1">, <section style="order: 2">, and <section style="order: 3"> how can I use querySelectorAll() to get the first, ie, that in which the value of order is 1?

Not sure how to get past this: document.querySelectorAll("[style]")
