title: How to trigger native screenshot function of iOS and Android via JavaScript?
body: <p>I am currently working on an Ionic Vue App and want to take a screenshot of the entire page. Since I have multiple canvases with different context types on the screen, famous libs like 'html2canvas' do not work for me. The cordova plug-in also was no success for me sadly.</p>
  <p>Is there a way to trigger the <strong>native screenshot function</strong> of a device via JS? The taskbar at the top as well as buttons at the bottom are allowed to be visible on the screenshot.</p>
  <p>My app is not designed to be used on PC, so I do not have to worry about this platform.</p>
