At the top of the page, you can see a CO2 clock that I want to remove. When I look at the source code, I see the link to the clock.
The clock was configured by a previous admin whom I unfortunately cannot reach.
Unfortunately, I haven’t found anything on how to remove the clock.
The banner disappears when I deactivate themes and theme components in safe mode. It is therefore probably custom code or a theme component added to the standard theme under /admin/config/customize/themes.
