Debian does not start with a graphical interface

I'm using Debian Buster and it starts in text mode so that for me to run the graphical interface I always have to run # startx on the command line. How do I start it directly in graphical mode? I saw in other questions that you have to edit the /etc/inittab file and change the run level to start in graphical mode, but apparently there is no such file or at least I didn't find it. Can you help me?
