Quick and dirty
After googling quite a bit I couldn’t find a satisfying out-of-the-box solution for cache clearing. I came up with a quick and dirty solution which you can find on stackoverflow.
Simply open a new tab, go to Chrome’s settings, press the right key combo, wait, close the tab and go back. I tested the script in November 2020.

Just beware that Chromium saves the last user settings. Hence only the first time you should uncheck “Cookies” so your login session doesn’t get deleted.
Simply add a default argument to the function and we are good to go.
