The regular expression tool is unable to locate and substitute a string that includes parentheses

Seeking help in identifying and highlighting a sentence within a paragraph (found in a textarea). The current method works fine for sentences without parentheses, but struggles with replacing strings surrounded by ""mark"" tags. Is there a way to modify the Regex pattern to successfully find and replace a string that contains parentheses? Should I first swap out all parentheses with ""/("" and ""/)"" before attempting to replace?

const text = "An economy is composed of suppliers (workers) and demanders (firms)."

const regex = new RegExp(text, "\d");
// regex returns: /The market for labor, then, is composed of suppliers (workers) and demanders (firms). /
        console.log("REGEX:", regex);
        let match = text.replace(regex, "<mark>$&</mark>");
        console.log("MATCH:", match);

Emphasize Text within Brackets

html:

<html>
  <body>
   <p id="text">"[The sun is shining (brightly) today].</p>
  </body>
</html>

JS:

function brackettext() {
  const t = document.getElementById("text").textContent;
  const regex = /(?:^[^\[]?[^\[]+)?(\[\w+\])/g;//retains brackets
  //const regex = /(?:^[^\[]?[^\[]+)?\[(\w+)\]/g;//removes brackets
  document.getElementById("text").textContent = t.replace(regex, "<strong>$1</strong>");
}
