Direct offer/rebates?

I was one of the fortunate few who put my order in a very long time ago, was guaranteed production & delivery for 2022 model, and then the delays hit. I was very glad to hear that Ford was going to give me a 2023 model and honor the 2022 price. The problem is I still have not heard anything about Direct offer/rebates to offset pricing increase. I’m supposed to take ownership of the truck sometime next week and have not gotten anything official from Ford and my dealer said I need a letter from Ford with the “certificate numbers”? Does anybody know more about this process?
