Fitness

I couldn't speak to this specific machine and machines aren't really my wheelhouse but a couple of great guys to follow on YouTube are Mike Israetel of Renaissance Periodization and Jeff Nippard. Both are really knowledgeable and speak in language that a layman can understand. Jeff is all about natural growth through "science-based exercise". Ignore Mike's nonsense or enjoy it, it's mostly put on. He is extremely knowledgeable and cuts through a lot of the bullshit and mysticism around hypertrophy based lifting and physical fitness. From there you could probably find a basic 3 day program centered around machines.

Edit: I should also say, beyond being safe, the most important thing is consistency. Pick a schedule that actually works for you, at least 2 but ideally 3 days per week, and do that every week and in 6 months you'll see noticeable results. The individual lifts matter much less for beginners.

In that case, maybe check if a nearby gym has free trials or affordable sessions with a coach.

Sometimes exercises are a bit unintuitive and need attention to specific movements.

Great, you have both back and leg exercises there then, with leg raise and chest flies. I'm wondering if it also allows leg curl, so you can train the other side of the thigh also.

You might want to add in bodyweight exercises in your routine to get a full body exercise. Like plank or situps for core, which I don't see any way to train with the machine.
