VS Code will expose the API to list all keys that an extension has stored in Secret Storage.

export function activate(context: ExtensionContext) {
  const keys: string[] = await context.secrets.keys();

  const value = await context.secrets.get(keys[0]); // a value that exists
}

We can use it to optimize the way we store / delete secrets.
