executing exe from CEP panel by clicking a CEP button

Dear PPro fellows,

Here is the code which runs CEP panel concurrently with my exe file (index.js file):

var csInterface = new CSInterface();
const exec = require('child_process').exec;
exec("myPath\\myApp.exe", function(err, stdout, stderr) {});

This code works just fine.

However, I'd like to start my myApp.exe after the user clicks a button.

What I tried to do is as follows:

I added:

var openButton = document.querySelector("#open-button");
openButton.addEventListener("click", openDoc);
function openDoc() {
    	const exec = require('child_process').exec;
	exec("D:\\Yaroslav2021\\anytex\\anytex.exe", function(err, stdout, stderr) {});
}

This doesn't work.

As far as I now understand node.js functions don't work in buttons so straighforwardly.  Could you hint me what to do? May be a single code line can solve this problem?

Yaroslav.
