How do I move apps to the dock in iOS 17?

Thanks. At this point I do not remember what apps the reset placed on my dock, although I believe that they were phone, message, safari and music, in that order. I have spent the last hour moving virtually all the apps from my home pages into the App Library, leaving only the ones that I really need to access quickly on the first home page. Somehow I was able to move the music app, which I never use, off the dock and move my mail app back onto the dock. Why I was not able to do that earlier (it would just bounce back onto the home page) is beyond me.

Thanks. I should have thought that one through before doing it. Resetting the home screen at least got my phone app back on the dock, but now the music app, which I never use, is there instead of the mail app that I used to have there, and none of the other apps that I had on the first screen and that I use all the time, are there any more. Oh well.
