Help! New to hot tub ownership

I just purchased a home that came with a hot tub. It’s a Jacuzzi brand. The previous owner left very vague instructions that say “turn jets on and put some shock in it every week”. They left me some shock, some chlorine, test strips and some de-foamer. That’s all. I did a quick test strip and all numbers are within the tolerance range as of two days ago. I don’t know what to do from here.

I don’t know how to tell what type of model it is. Google said I can remove the corner panels and then front panel under control board but those aren’t budging and I don’t want to break them. I’m in need of a new cover. I understand this is very vague commentary. I stopped by my local spa store and they tried selling me every chemical under the sun.
