Autostarting HA on WSL2 in Windows

Morning all, I am installing HS on a Windows machine using the method that uses WSL2, as described here: Windows - Home Assistant.

That is all running tickety-boo and I have Windows automatically starting WSL2 on bootup using the the steps described here: How to Run WSL2 at Startup on Windows | by David Littlefield | The Startup | Medium

However, this does not automagically start the HA program itself: it just starts WSL2 running in the background, not the HA program running as the homeassistant user.

What’s the preferred method to do this? I see various things about using systems and init, but I am not a big Ubuntu user, so I am not sure which is the preferred way to go. Thoughts?
