YJME is not cached

Hello, good morning.

I installed the buster template on my local server. And I'm trying to look for the option in the YJME module to activate the cache and it doesn't have one.
The problem is that the module is not saved in cache and it is essential to do so because the web consumes much more resources and takes longer to load.
How can I activate the cache of the module?
Thank you, very much.
