How do I access the name_with_location_descriptor field on the /page endpoint on the Graph API?

The page Graph API Reference has a field named name_with_location_descriptor, which is defined as:

The name of the Page with its location and/or global brand descriptor

and has a tooltip which states:

This field is only accessible in v2.2 or later

However, I can't make that field appear on any Pages I try, using both v2.2 and v2.3. What's the secret for making this field show up? (And while we're at it, what should I expect to find in that field?)

To provide some more information, the field doesn't even appear to be available on the root /<page-id> endpoint but only as a child node in global_brand_children. Here's a Graph API explorer link showing that the field is available (albeit grayed out) for this page, which has global brand children. I've also tried toggling the version to v2.2 with no change.
