Cannot add command line arguments via java.test.config

I'm trying to add listeners when running testNG tests using the Java Test runner.

In my settings.xml I've added:

"java.test.config": {
"name": "RunWithContinue",
"workingDirectory": "${workspaceFolder}",
"args": [
"-listener", "org.test.TestFilter"
]
},

But when I run:

[ERROR] {"name":"error","attributes":{"message":"Failed to run TestNG tests","trace":"java.lang.ClassNotFoundException: -listener
at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:581)
at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178)

at com.microsoft.java.test.runner.testng.TestNGLauncher.execute(TestNGLauncher.java:32)
at com.microsoft.java.test.runner.Launcher.main(Launcher.java:57)
"}}

It seems all args are expected to be a Class/Method name, even though it seems to be the only place to pass TestNG command line arguments:

Is there a workaround?

Start with the failing stack trace in TestNGLauncher.java, especially parse and getClassName, then inspect how Launcher.java receives settings from java.test.config. Reproduce the case with the shown TestNG listener arguments. Done means the configured arguments are handled as intended by the test runner and the listener configuration no longer produces a ClassNotFoundException.
