Unable to Cache my WordPress version 5.9

I’m unable to find the cache option to clear cache on the backend for my wordpress version 5.9
the problem am currently facing is that whatever changes we are implementing in the website, is not being reflected on the live (production) website. Kindly advise what to do and how I can proceed with resolving this issue, either if clearing cache is the resolution or there is something else i should be doing.

thanks
