Envato Elements: How can I edit or delete licence projects?

I subscribed to Envato Elements and understand the principle of adding downloaded items to a project.
It happens, however, that selected items should ultimately not be used on the assigned project or that the project is not completed.
Such effects create a long list of “dead projects” that are no longer relevant and for which licensing would no longer be required.
How can I edit this list of projects or delete individual projects and their licensing?
