How do Warlock pacts on Theros work?

The Mythic Odysseys of Theros lists, for each of the gods, the domains most associated to them. As well as this is listed the suggested classes. Here is an example:

Athreos’s Champions

Alignment: Usually lawful, often evil
Suggested Classes: Cleric, monk, rogue, wizard
Suggested Cleric Domains: Death, Grave (described in Xanathar’s Guide to Everything)
Suggested Backgrounds: Hermit, sage, sailor, urchin

Obviously this isn’t an exhaustive list.

However, I haven’t found a similar mapping for the Warlock Pacts or Patrons.

Does any information on this exist in the book (that I’ve missed) or is it available elsewhere?

If not, which gods/monsters/entities make sense for each pact and patron?
