That should be obvious: get my contacts from outlook.com (OWA) synced Outlook 2016 or Outlook 2019.

Call me stupid; I can't get neither my contacts , nor schedules  from my outlook.com account to show up in Outlook 2016 for Mac or Outlook2019 for Windows.
All my contacts and schedules are on https://outlook.live.com/people/, and https://outlook.live.com/calendar I can see them in Outlook for Android on my smartphone but I can't see them in the desktop apps.
What are the steps to initiate the contacts syncing on desktop apps?

I assume, I should define an Outlook account instead of an eMail account with the Outlook.com address, but I can't find a way to define an account that way.
