Sending Data to a Form inside a Lightbox

The lightbox still won’t open. Does it have anything to do with the fact that the buttons are inside a repeater element. If I change the ID of one button, they all change. How can I write code to distinguish which button is pressed?

Here is the updated code:

export function repeaterButton2_click(event, $w) {
	const data = {
		"Item Name": 'Hello world',
		"Details": 'Text'
	};
	wixWindow.openLightbox('SideBox', data).then(dataBack => {
		console.log(dataBack);
		console.log('Bye!');
	});
}

Thank again.
