Persistent chat history with Cosmos DB is not working

- [x] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

I enabled the persistent chat history feature following the provided guide (setting USE_CHAT_HISTORY_COSMOS to true and running azd up). However, when clicking on "Open chat history" in the web app no history is displayed, even after sending some questions and getting answers.
When deactivating this feature and activating the client-side chat history, it works and the chat history can be viewed.
The environment variable AZURE_COSMODB_ACCOUNT is filled correctly and a respective Cosmos-DB account was created. However, no data can be seen there.

Any log messages given by the failure

TIMESTAMP - IP_ADDRESS:0 - "POST /chat_history/items HTTP/1.1" 401

Expected/desired behavior

The history should be filed as soon as I receive the answer on my 1st prompt from GPT.

OS and Version?

My local device has Windows 10 but I'm running the application on Azure.

azd version?

azd version 1.11.0 (commit 5b92e0687e1fa96dfc8292f4b900c0c58610b6a5)

This feature allows authenticated users to view the chat history of their conversations, stored in the server-side storage using [Azure Cosmos DB](https://learn.microsoft.com/azure/cosmos-db/).This option requires that authentication be enabled. The chat history will be persistent and accessible from any device where the user logs in with the same account. To enable server-stored chat history, run:

Did you also enable authentication?

Yes I did

The problem was, that we needed to add admin consent to the server app as mentioned in the last point of the Troubleshooting section of the guide

Is there a possibility of making troubleshooting this issue more straightforward? (Currently the only options are asking the admins whether they implemented that policy or trial and error).
It's also totally unclear why that is the case.
