Antonym for jinx

After clarification of the question, what's being looked for is a verb that's the antonym of jinx, and used in a superstitious context.

I believe that invoke satisfies those criteria:

[Merriam-Webster]
2 : to call forth by incantation : CONJURE

// Nietzsche is so complex that he can be invoked in support of many outlooks, some of them brutal or nihilistic.
— Thomas Nagel, New Republic, 14 Jan. 2002

// There are some people who commit murder as a way of invoking the death penalty. Capital punishment can sometimes, then, be equivalent to suicide.
— George Freeman Solomon, People, 17 Jan. 1977

Used in the example sentence in the question, and paraphrasing it slightly so that it makes sense with the word, it would look like this:

""Woohoo! The return to office date got pushed back, when I said it wasn't going to happen I invoked that result."

A similar word is evoke, but I personally feel it doesn't have quite as active a sense of summoning something real as does invoke, and instead is more commonly associated with recollection.

Google Books NGram Viewer also indicates that invoke evil spirits is about three times as common as evoke evil spirits:
