How to render the frontmost AudioSuite plug-in

This is a reply to a request by Lars Rasmussen on Facebook:

// This command renders audio in the frontmost AudioSuite plug-in
/* Script includes code from Oliver Momm */

// Function to set Pro Tools frontmost via AppleScript
function setPTfrontmost() {
    sf.system.execAppleScript({
        script: 'tell application "System Events" to tell process "Pro Tools" to set frontmost to true'
    });
}

// Set Pro Tools frontmost
setPTfrontmost();
sf.wait({ intervalMs: 50 });

// Render frontmost AudioSuite plug-in
var asWin = sf.ui.proTools.getFloatingWindowWithTitleStartingWith('Audio Suite:');
asWin.getFirstWithTitle('Render').elementClick();
