Action Extension Scripts appear not to be registered with Katalon Recorder

Katalon Recorder 3.6.12 (Chrome) appears not to register any action extension scripts (those named as doSomething). The provided doTypeRepeated action extension function, for example, in sample-custom-commands.js in katalon-recorder-samples is not available to tests (although the getTextLength and assertValueRepeated functions are).


Setting a breakpoint in Chrome debugger on the doCommands function in command-receiver.js in the plugin
shows that any action extension functions do not appear in the handlers list. I’m guessing they should.

The resulting error is

Is this a recognised bug? And is it in the process of being resolved? Many thanks.
