does Nitter use Twitter credentials?
For example, the graphTweet route (83h5UyHZ9wEKBVzALX8R_g/ConversationTimelineV2) only works for me on a signed-in user, yet from the source code it doesn't seem like credentials are being sent with the Fetch requests to the API. However, nitter.net is still able to return tweets on /status/ routes which use this endpoint, so I'm not sure how this is happening.
