linux – Best practice to store code on Google Cloud VM instance?

I have a GCP compute engine VM instance. Under /home folder there are multiple users and they all have their respective SSH keys:

(base) user1@a100-80gb:/home$ ls
user1  user2  user3  user4  user5

I want to create a /code folder for managing multiple codebases and everyone can access it. What is the best practice for such a task?

Is creating a /code folder under /home the best way? But if I do so /code folder does not have its own ssh key that I can add to GitHub(Or I can just ssh-gen one under the /code folder?) Something like:

(base) user1@a100-80gb:/home$ ls
user1  user2  user3  user4  user5 code

For reference, here’re the folders under /:

(base) user1@a100-80gb:/$ ls
bin   dev  home  lib32  libx32      media  opt   root  sbin  sys  usr
boot  etc  lib   lib64  lost+found  mnt    proc  run   srv   tmp  var
