Example using CMS
Whenever you update the item lists of the Provider entity and Laptop entity, the Text Block will automatically update corresponding Quick Reply buttons. It means that when a user selects a Quick Reply button, laptop-list blocks will automatically display suitable laptops. You don't need to make a change or add any other blocks in Flow Editor.
For example, we try adding one more item (Microsoft) into the entity Provider. Meanwhile, add one more item (Surface Pro) which is linked to Microsoft Entity into the Laptop entity. These recent changes will automatically be updated in the Flow Editor.
