scheduling of sending messages (SMS / I message)

How is it even possible that on a Iphone 11pro, which costs more than $ 1000, there is no possibility of postponing sending a message?

can't I find it? I am asking for help, I do not believe that I have to buy separate applications for that purpose. Ten years ago I had this option in a regular Alcatel phone. Which was not even a smart phone... 🙄
