From the Steps tab on the job's configuration page, you can create an Application Extension Package job that packages an extension build artifact and an Application Extension Deploy job that deploys the build artifact to an Oracle Cloud Applications development instance, production instance, or any other instance. You can then add these jobs to a pipeline and run them in sequence.

Deployed extensions can be viewed from the Manage Extension Lifecycle page and can be deleted manually from there too, if needed. See Manage Your Published Extensions in Extending Oracle Cloud Applications with Visual Builder Studio.
