Info: How to pass in a message from another command to the webview?

I have tried exposing a ``postMessage`` function in ``NextViewWebpanel`` class and then posting a message to ``this.panel.webview.postMessage``, but I can't get it working. I'd like to update the VSCodeAPI State.

What is the best practice in updating the state of the webview from another command?

Some context:
I'm trying to pass text from the editor to the webview.

Thank you in advance!

Read the NextViewWebpanel class and the command that is meant to pass editor text to the webview, then trace the call to this.panel.webview.postMessage and the VSCodeAPI state update. The issue does not name a file or test, so completion would require defining and verifying a working message flow first.
