How to apply one function to all elements with the same class

I want to click on any of the 3 buttons, and they all will change their background colors at the same time. What is missing or needed to change in my code, for the addEventListener to be able to apply in all elements with the same class?

const one = document.querySelectorAll('.one');

one.forEach((element) => {    
    element.addEventListener("click", () => {
      if (element.style.backgroundColor = "#DCDCDC") {
        element.style.backgroundColor = "#56F1FF";
      } else {
        element.style.backgroundColor = "#DCDCDC";
      }
     })
 });

.one {
  background-color: #DCDCDC;
}

.one:hover {
  background-color: #56F1FF;
}

<button class="one">Catch</button>
<button class="one">Change</button>
<button class="one">Choose</button>
