The Toast component introduces:

• <%= code("app/helpers/components/toast_helper.rb") %>
• <%= code("app/javascript/controllers/ui/toast_controller.js") %>
• <%= code("app/views/components/ui/_toast.html.erb") %>

<%= code("render_toast") %> accepts two keyword arguments, one for the <%= code("header") %> and the second for the <%= code("description") %> or body of the toast. An optional 3rd argument can be provided for an <%= code("action") %> element like a button.
