Inputs on Cache Layer Extension for read actions

I wish to write an extension to enable caching on certain read actions that define cached? true inside a read action.

How would I idiomatically proceed for the same in Ash? I wish to use Cachex for caching.

Ideally, I am thinking

use Ash.Resource, extensions: [MyCacheExtension] 

... 

actions do 
    read :read_by_id do 
    ... 
        cached? true
    end
end

or a separate cache block which could be more flexible.

cache do 
   activate_for :read_by_id , ttl: 3000 # ms
end
