I'm using the firefox extension [metrication](https://addons.mozilla.org/en-US/firefox/addon/metrication/). I only ever use it via its entry in the right click context menu, therefore I would like to remove its icon from the url bar to gain more space:

I tried the suggestion from https://www.reddit.com/r/FirefoxCSS/comments/zcapzr/add_css_to_remove_addon_icon_from_the_address_bar/
I looked up the id of the extension in about:debugging#/runtime/this-firefox

and added
```
#pageAction-urlbar-_670400a3-bbd4-4846-88c9-929844eee39a_{
display: none !important;
}
```
to my `userChrome.css`. Unfortunately, the icon is still there after restarting the browser.
I also tried
```
#pageAction-urlbar-_metrication@deltamikecharlie_{
display: none !important;
}
```
just to cover all bases, but this did not remove the icon either.
I suspect the name of the element I am trying to change is not correct. How to get the correct name? For "normal" elements on a webpage, I would use the element picker to look up the name, but how to do this with UI elements?
I'm using
- Firefox 102 ESR
