Is your feature request related to a problem?

Like many others we cannot sign in due to the risk of inadvertantly syncing sensative data to the cloud.
With the desktop app you can choose to continue without signing in, using the "lightweight Postman API Client".

There does not appear to be equivalent capabiltiy in the VS Code extension.

Describe the solution you'd like

Similar to the desktop app, please add a "continue without sign-in option" to the extension.
