Obtain links from buttons on GAS spreadsheet

I have created an example of creating a menu called "View URL" using Google Apps Script.

function onOpen(){
  vars = SpreadsheetApp.getActiveSpreadsheet();
  SpreadsheetApp.getUi()
    .createMenu ("View URL")
    .addItem("View URL", "alertUrl")
    .addToUi();
}

function alertUrl() {
  vars = SpreadsheetApp.getActiveSpreadsheet();
  varurl=ss.getUrl();
  SpreadsheetApp.getUi().alert(url);
}

A menu similar to the following appears: ...

Click to display a window similar to the one below and you can copy the URL.

For your information.

I'm not sure what the specifications are, but
Maybe Google Apps Script will solve this problem.
