Migration Assistant not working

I have two M1 MacBook Pros running 14.2.1. I am trying to transfer the data from one computer to the other using **Migration Assistant**. I have tried connecting via the wireless network. I have tried using a 10GB USB-C cable and no matter what order I try to do this in neither one of the computers recognizes the other and I am not able to transfer the data. I have also tried doing Target Disk mode, with hopes I could just copy the files over and it does not work. I hold down the T key and boot up. It simply goes to the login screen. I am not sure what I am missing but I know that I am not succeeding. I welcome guidance. **Updated:** One thing that does work is if I connect a Time Machine. That is recognized and allows me to move forward.
