How does one include an additional field in the results of a Directory search?

Summary: Hello all,

We have a requirement to add another field in the search results of the Directory's results.

Currently, the delivered fields are Display Name, Business Title, Work Email Address and Person Number.

We must add Work Phone Number.

I found DOC ID's 2545015.1 & 2535339.1, but they are both about removals of fields - not an addition of a field.

Regards,

Shant
