Is it more accessible to use <button> or <a> to open / close a modal?

Question

In my opinion, buttons are used to perform functions, and links are used to move the user to another page. But what is best in terms of opening and closing a modal?

<a id="testModal" href="#">Open Modal</a>

or

<button id="testModal">Open Modal</button>
