How to run different DE along with cosmic

How do I run another DE along with cosmic. I'm running alpha6 and would like to use some apps which don't yet run with cosmic (some steam games)

What is meta name for plasma for e.g. (will it overwrite greeter)

Pretty much. You can have GDM start the session for Cosmic, but not vice versa afaik.
- You can choose a session in cosmic-greeter through a dropdown.
I run 24.05 Alpha, I just did "sudo apt install gnome-session", I can choose between COSMIC and GNOME in the COSMIC greeter every time I login. You can probably do the same with Plasma.

Haven't needed to login to GNOME since last year though.
