Question about withdrawing

I'm looking to withdraw bitcoin into a hard wallet, however I am unfamiliar with the process. Do you really just go on your phone and put in the amount of the withdrawal and the address? It seems strange that you're withdrawing it into a hard wallet without actually needing the touch the hard wallet itself, which is making me suspicious that I may be overlooking something. Do you really only need to plug in the hard wallet to verify that the bitcoin made it in?
