I am writing a visual studio code extension and I'd like to be able to open a browser window with a specific url in response to a command. I know that Electron has a BrowserWindow class but it appears that the Electron API is not accessible from a vscode extension.

I'd prefer the browser window to open within the tool but I'd be ok with opening the web page in my default browser if it is not possible.

How does one open a web page from an extension?
