Hi everyone! I'd like to implement the search widget in my app. A user can get grounded answers with links to documents from a Cloud Storage. The problem is, that I need signed urls and I cannot find any information if it is possible to configure the widget so that I can get signed urls. Also I'd like to implement the chat widget with authenticated access, but for that a user has to have a google account. Is there any opportunity to authenticate the user through for example the Firebase Auth?
