Before uploading to the Teams admin center, edit manifest.json:
  1) Replace <REPLACE-WITH-YOUR-APP-GUID> with a new GUID for the app.
  2) Replace <REPLACE-WITH-YOUR-BOT-APP-ID> with the Azure Bot App ID (appears twice).
Or: set TEAMS_APP_ID and MicrosoftAppId on the RunningTab server and re-download this zip.
