Getting a 302 response when trying to list messages

### Describe the Bug We're receiving a 302 response when trying to list direct messages via `reddit.inbox.messages()`. This used to work, but it may have been broken when Reddit introduced the new Reddit Chat. 🤷‍♂️ ~As an alternative, we tried using `reddit.inbox.all()`, but it seems like it won't return any Messages, only Comments.~ **PS:** I'm sorry if this is not a `praw` bug, but rather a Reddit API issue. I am just trying to learn more about this issue. ### Desired Result Return the `Message` objects. ### Code to reproduce the bug ```Python reddit = praw.Reddit( client_id='<client_id>', client_secret='<client_secret>', user_agent='<user_agent>', refresh_token='<refresh_token>' ) reddit.inbox.messages(limit=25) ``` ### My code does not include sensitive credentials - [x] Yes, I have removed sensitive credentials from my code. ### Relevant Logs ```Shell prawcore.exceptions.Redirect: Redirect to /login/ (You may be trying to perform a non-read-only action via a read-only instance.) ``` ### This code has previously worked as intended Yes ### Operating System/Environment macOs Sequoia 15.6.1 ### Python Version 3.11.13 ### PRAW Version 7.8.1 ### Links, references, and/or additional comments?
