   You’re going to need a network connection. It might be possible to   
   establish one over USB but ethernet or wireless will be a lot more   
   practical.   
      
   What OS is the laptop running?   
      
   If the laptop is running Linux then SSH and X11 forwarding is the most   
   common option. You can enable it in your client’s config file (see ‘man   
   ssh_config’ for documentation) or with the ‘ssh -X’ command-line option.   
   Within the SSH session, run your graphical application(s).   
      
   If the laptop is running Windows then you have a couple of options.   
      
   (1) Enable WSL2 on Windows. Use SSH and X11 forwarding from inside a   
       WSL2 shell, exactly as described above. This is my usual approach.   
      
   (2) Set up a remote desktop server on the Pi and use the Windows Remote   
       Desktop application to connect to it. You get a complete desktop   
       session this way.   
      
       On anything Debian-derived, to install the server:   
      
         apt install xrdp   
      
       If you don’t have a desktop environment (or some other kind of X   
       session) installed you’ll need to install that too. If it’s a normal   
       RPi OS install then you probably already have one.   
      
   Notes:   
      
   * I mostly do the above with x86 targets. Pi is not different in any way   
     that’s relevant, though.   
      
   * Other approaches exist (e.g. VNC); I’ve limited myself to the ones   
     that I use.
