Folks, I am trying to get access to a `FileSystemTree`  instance from my action. But, I haven’t succeeded yet. I have tried the following,

*Attempt 1*
```val fileSystemTree = e.getData(FileSystemTree.DATA_KEY) // returns null```
*Attempt 2*
After looking into implementations of `LightEditGotoOpenedFileAction` and `NewFileAction`, I tried extending my action from `com.intellij.openapi.fileChooser.actions.FileChooserAction` . However, the extended action is always disabled on the UI (Despite overriding the `update` function).

Also, my action cannot be `DumbAware`, therefore even if using a `FileChooserAction` gave me an instance of the `FileSystemTree`, it wouldn’t be relevant to my use case. Pointers are appreciated. Thank you in advance.
