I have a social media setup where a User resource can like or block an other User resource. Here is the beginning of the resource:

defmodule Animina.Accounts.Reaction do 
  use Ash.Resource,
    data_layer: AshPostgres.DataLayer

  attributes do
    uuid_primary_key :id

    attribute :name, :atom do
      constraints one_of: [:like, :block]
    end
  end

  relationships do
    belongs_to :sender, Animina.Accounts.User do
      allow_nil? false
      attribute_writable? true
    end

    belongs_to :receiver, Animina.Accounts.User do
      allow_nil? false
      attribute_writable? true
    end
  end

I want to like, unlike, block and unblock from within our own code and open an external JSON-API for 3rd party software to do the same.

Is it a good idea to create custom actions (like, unlike, block and unblock) for that? If yes, how? If no, why?

The documentation is too abstract for a mediocre programmer like me who works best with examples.
