How do I make macOS native Contacts the default application for adding a contact instead of Microsoft Outlook's Contacts?

Question

My Outlook Version is 16.14.1.

Elaboration:

• I'm in the native Messages client. Someone sends me a contact through iMessage.
• I add that contact through the UI in Messages.
• Expectation: the contact gets added to my native macOS Contacts. Reality: the contact gets added to my Outlook contacts.

I don't recall doing anything notable during install that made this happen.

Oddly enough the Address Book.app has no GUI method of setting itself as the default handler for addresses, annoying.

There is a work around that may work for you. Drag any one contact out to the desktop. You will get a .vcf file. Get Info on that file (select it > File Menu > Get Info) and under the "Open With" section choose Contacts.app and then click on the "Change All" button and affirm your choice to make .vcf files open with the built-in address book app.

It's a bit of a kludge but should work for you.
