Clear cache tool missing

I’m trying to clear templates cache. The Craft CMS 3 documentation says:

 You can also manually clear all of your template caches from the Settings page, using the “Clear Caches” tool.

When I go into Settings, I don’t see any options to clear the cache there, nor is it within any of the other options there (General, Sites, Routes, etc). Do I have to enable the utility somehow? Thanks in advance for your help.
