How can I disable the Document Exchange feature?

Only Recruitment Managers and Hiring Managers can disable the document exchange. Go to "Recruitment" in the left sidebar > Click on "Vacancies" > Select the vacancy > Then click  on "Applicants Pipeline" > Select the applicant > Click on "Disable" in the "Document Exchange" section. You can disable both drives ("Share with Applicant" and "Share with Company") at the same time or you can disable them individually. Note that if you disable any of the drives any files within that drive will be permanently deleted.
