How to Add class via keyboard shortcut

For stream deck, I want to create some custom keyboard shortcuts for Bricks Builder that adds the classes like (.bg-dark .bg-light etc) to selected element.

Anyone can help to make below code work

JavaScript Code:

document.addEventListener(‘keydown’, function(event) {
// Check for the desired key combination (e.g., Ctrl + Shift + D)
if (event.ctrlKey && event.shiftKey && event.key === ‘D’) {
// Prevent the default action
event.preventDefault();

    // Find the selected element in Bricks Builder
    const selectedElement = document.querySelector('.bricks-element-selected');

    if (selectedElement) {
        // Add the .bgdark class to the selected element
        selectedElement.classList.add('bgremove');
    } else {
        console.log('No element is currently selected.');
    }
}

});
