Question

I want to add the 'enable proposed API' argument automatically. when calling the activate function in a VSCode extension. How can I achieve this?

1. Ctrl+Shift+P -> Preferences:Configure Runtime Arguments:

2. when calling the activate function Add this argument.(argv.json):

Installed Extension -> Extension Activated -> add enabled-proposed-api=["myExtension"] automatically -> enabled-proposed-api applied.
