It's a new security measure introduced since Magento 2.3.4. The goal is to remove the opportunity for Remote Code Execution (RCE).

In the new method, you need to create the XML changes in a file, and Magento shows the options to customize the CMS page. You can create your XML files inside the folder below, and the name of the file must follow the syntax mentioned in the Magento 2 DevDocs Compose the layout update in the XML section.
