Eduardo is building a new HTML5 creative in Google Web Designer. How can he ensure that it will work with Studio?

To ensure an HTML5 creative built in Google Web Designer (GWD) is compatible with Studio, Eduardo must set the file's environment to DoubleClick. This setting automatically incorporates the necessary Studio-specific libraries and configurations into the creative, enabling it to communicate correctly with the Studio platform for trafficking and reporting. Including a DoubleClick component is not a standard or sufficient step for overall Studio compatibility; it refers to specific interactive elements. Adding Studio files to the library is unnecessary as the environment setting handles this integration. Setting the ID to "DCLK" is not a valid method for establishing Studio compatibility; the ID is typically for internal tracking or element identification within the creative itself.
