To include a grid or form in an admin page layout using the UI Component, the correct approach is to use the<uiComponent name="example_listing"/>within a<referenceContainer name='content'>block of the layout XML file. This method directly references the UIcomponent's configuration file (e.g.,example_listing.xml) which defines the structure and functionality of the UI component, such as grids or forms. This configuration file is located under theview/adminhtml/ui_componentdirectory of the corresponding module​​.
