How to invoke JavaScript/ExtendScript for Premiere Pro CC in Mac OS

Looking for a way to run JavaScript aka ExtendScript in Premiere Pro CC

Here's what I've got for other Adobe Apps, using AppleScript:

tell application "Adobe After Effects CC 2015"  activate  set SomeExtendScript to "ThisVariable='Runs This Js Code';"  DoScript SomeExtendScript
end tell


tell application "Adobe Photoshop CC 2015.5"
  activate  set SomeExtendScript to "ThisVariable='Runs This Js Code';"  do javascript SomeExtendScript
end tell


tell application "Adobe Illustrator"
  activate  set SomeExtendScript to "ThisVariable='Runs This Js Code';"  do javascript SomeExtendScript
end tell

But so far nothing for Premiere.

tell application "Adobe Premiere Pro CC 2015"  activate  set SomeExtendScript to "ThisVariable='Runs This Js Code';"  -- Does not work: DoScript SomeExtendScript  -- Does not work: do javascript SomeExtendScript  -- Does not work: do script SomeExtendScript
end tell
