In the documentation for `/filter` the `watching_first_post` filter is mentioned.

> [@Filtering topic lists in Discourse](https://meta.discourse.org/t/filtering-topic-lists-in-discourse/375558/1):
>
> **`in:watching_first_post`** - Topics where you watch first post only

However, this does not seem to do anything.

It’s also not available as a regular `?state=` parameter, while watching etc are.

Looking at the [code](https://github.com/discourse/discourse/blob/db67a0841e8e14ae70de0890441f8158c50ae3c9/lib/topics_filter.rb#L746-L755) it seems that it uses `TopicUser` and [I don’t think that works](https://github.com/discourse/discourse/blob/main/lib/notification_levels.rb) for watching\_first\_post if I remember correctly?
