Cache wp-admin problem and questions

I’m about to start working with caching of wp-admin and is trying to find out about how LS Cache is doing that and how I can config it. But can’t find much information. There is only a checkbox saying “Cache Wp–Admin“. But no information about what type of cache that means. Object cache? Page cache? No information in the documentation about this. I have ticked that box and saved but not sure if anything is working. I’m monitoring what’s going on with the Query Monitor plugin and those object cache queries I have are all executed. And I have Redis activated so should have been saved and fetched from the cache instead of running the database query.

So what is “Cache Wp-Admin” really doing?

And what I would like to achieve is some kind of precaching objects when saving. Would be good if I could use some kind of cache tags or something and update all cached objects for specific cache tags on save.
