getChatMessage - Forbidden message "Invoked API requires Protected API access in application-only context" in list messages in a chat

Question

Hi Microsoft Support,

Please help to take a look at the below issue. I created a python daemon program and try to get the messages from Microsoft team chat. I followed the steps in the "list message in a chat" API. However, I got the error message "Forbidden" - "Invoked API requires Protected API access in application-only context... "

https://docs.microsoft.com/en-us/graph/api/chat-list-messages?view=graph-rest-1.0&tabs=http

I have setup a sandbox, registered an application, add the Chat.ReadAll, Chat.ReadWrite.All, Chat.Read, ChatReadWrite Permission and granted the admin consent to these permissions. I also submitted the "request form" for the Protected APIs in Microsoft Teams 2 weeks ago.

I am getting the Invoked API requires Protected API access in application-only context - forbidden error message.

Is that anything I missed or something incorrect. Thank you.
