There’s no mention of it on the docs, and the docstring is not helpful either.

```auto
initialize(FPMIApp) → void

null

Parameters:
    FPMIApp - No description provided.

Returns:
    No return value.

```

Is it deprecated or is it only missing the docstring?

Thanks.

There’s no purpose to calling it. It has to be public for internal reasons, but really doesn’t belong as a scripting method.
