Ubuntu 22.04.1 LTS on the XPS 13 9310

I see that the XPS 13 Plus is Ubuntu certified. Nice to see, but what about the 9310?

The 22.04.1 LTS popup showed up on my machine today. I want to upgrade, so I went through the screens, but it says that the Dell-Linux-Assistant will be removed. How do I get that back? Is there any support for this machine to maintain the BIOS updates, drivers, etc?

Has anyone just jumped right in?
