So, I'm not really sure if there aren't certain particular upload settings enabled, but the long story short is that most common file extensions are hidden from the resources name.
This makes it difficult to filter them in the search box.
On the other hand, all files do get at least an icon on their side specific to their format (or I don't know then if there isn't a more elegant api or something).
After inspecting the page (and putting aside the website domain) I could spot these in the img src:
../theme/image.php/boostcustom/core/1683807935/f/pdf-24
../theme/image.php/boostcustom/core/1683807935/f/spreadsheet-24
../theme/image.php/boostcustom/core/1683807935/f/jpeg-24
../theme/image.php/boostcustom/core/1683807935/f/powerpoint-24
../theme/image.php/boostcustom/core/1683807935/f/text-24
(the last one might or might not be used even for unknown formats, I couldn't cross-check)
