Hi there. You can register your custom controller/action in rails admin. In config/initializers/rails_admin.rb you can register a custom actions, something like this:

# Register new action
module RailsAdmin
  module Config
    module Actions
      class MyAction < RailsAdmin::Config::Actions::Base
        RailsAdmin::Config::Actions.register(self)
        register_instance_option(:member) { true }
        register_instance_option(:visible?) { true }
        register_instance_option :controller do
          # describe response here. You can use standard Rails methods like render or redirect
          proc { render json: '123' }
        end
        register_instance_option(:link_icon) { 'fas fa-pencil-alt' }
        register_instance_option(:pjax?) { false }
      end
    end
  end
end

RailsAdmin.config do |config|
  ...
  config.actions do
    dashboard
    index
    new
    show
    edit
    delete
    show_in_app
    my_action # add the action
  end
  ...

Then you will see this new action for your models. Hope this will help.
