What should i do after changing theme?

I am currently in the process of changing the theme on my WordPress blog.

Given that I utilize the Litespeed Cache plugin, I understand that it is crucial to purge the cache after changing the theme.

As a beginner, I am a bit uncertain about which specific button or option I should select to ensure a proper cache purge: https://i.ibb.co/Rpmc56Y/IMG-20231211-105236.jpg

There is so many options and i am confused.

Could you kindly provide guidance on the recommended steps or buttons to press within the Litespeed Cache settings after a theme change?

Your assistance in this matter would be greatly appreciated.
