The part after the hashtag is called a [URI fragment](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/Identifying_resources_on_the_Web#fragment). Unfortunately, Tampermonkey [does not allow you to match hashtags](https://github.com/Tampermonkey/tampermonkey/issues/1274).

This is arguably for good reason. The hashtag can easily change (and for single page applications, often does easily change) without a page reload. Since userscript managers load their scripts when the page loads, they simply *can't* match based on the URI fragment.

Therefore, you will have to check for the fragment in your script's code. It shouldn't be more difficult than just checking [`location.hash`](https://developer.mozilla.org/en-US/docs/Web/API/Location/hash)
