Content Cleanup error

Hi, I’m trying to run the cleanup script:

But I get the error Call to undefined method Kirby\Cms\App::models()
on

$models = $kirby->models();

why is this happening?

thanks a lot in advance!

The version of the script in the current docs is for Kirby 4, you can find the old script in the 3.9 docs: Cleaning up content files | Kirby CMS
