"Trusted Add-in Catalogs" in the Trust Center settings of Outlook is missing on my system.

Question

Microsoft Office Dev Center has an article called "Host an Office Add-in on Microsoft Azure". In step 4 of the section "Add the file share to the Trusted Add-ins catalog", they state that a shared folder needs to be added to the Trusted Add-in Catalogs.

The entry for "Trusted Add-in Catalogs" or "Trusted App Catalogs" is missing from the dialog on my system. I have Office Outlook 2019.
