I see that folks are trying to be helpful here, but I think that you're making it far more complicated that it needs to be. ZHA supports the SLZB-07, and the manufacturer supports ZHA. It seems to me that the path forward here is to figure out how to create automations first, which is not exactly straightforward. It'll be easier to figure out the issue if you can point to exactly what's not working, if anything.
Otherwise, there's a strong chance that if you get the adapter working with Z2M, you'll be back at square one trying to create an automation, but more frustrated.
