Delve Profile for Personal Landing Page

I am trying to add custom user property in the SharePoint Admin Center to display in the Delve personal profile.  I've added a custom property as a string, URL and HTML and neither appear in Delve, nor do they appear in the Search schema.  Is it possible to add these custom properties to Delve?  If so, how do I customize the page to display the new properties?  Thank you for any assistance you can offer.
