If a custom object needs to be committed to a package, which step should you follow?

Flagging the custom object in the User Story is essential because it helps to track what changes or components are intended to be included in the package. By marking the custom object in the User Story, you ensure that it is explicitly considered for deployment. This step is critical for maintaining clarity in version control and ensuring that team members involved in the project are aware of what is being included in the package.

The other options do not provide a direct way to ensure that the custom object is properly tracked and included in the package. For instance, selecting the object from the Scratch Org Wizard is more about the creation and setup of the Scratch Org rather than the preparation of components for packaging. Reviewing the metadata load process pertains to how metadata is deployed rather than the specific actions needed to commit a custom object. Accessing the DX Panel for options may provide additional functionality but does not specifically address the requirement to commit the custom object as part of package preparation.
