Syntax highlighting of javascript for ColdFusion Builder

Question

How can we edit or install JavaScript syntax highlighting for ColdFusion Builder Version: 3.2.1?

Let, const and the compact arrow function aren't highlighted.

function foo(){
    const x = "no highlighting";
    let x = "no highlighting";

    const materials = [
      'Hydrogen',
      'Helium',
      'Lithium',
      'Beryllium'
    ];
    
    console.log(materials.map(material => material.length));
}
