I don't think there's anything wrong with this. If your management had a problem with it, they would have said something. I don't think you "owe" anyone anything that your management has not asked or required you to give.
At one point in my career I was working 90+ hours per week, and while I learned a lot in that time (and at least convinced myself I was having fun), the end result was burnout. These days I work less than 40 hours a week. My management is more or less fine with that, and I'm fine with not getting stellar perf reviews, big raises or equity grants, or promotions. I've also been at my current company for a while; I've already done the 60-hour work weeks here in the past, and contributed a lot. I still contribute and add value, but less, and on my terms.
Just be sure what you're doing is sustainable. If you have to leave your current job for any reason (new manager who sucks, layoffs, company folds, whatever), will you be able to get good references so you can get another job? Will you be able to keep up the same low level of work at a new job? Will you even be able to pass interviews for a new job since you aren't really growing yourself technically?
Also be sure that the company is large enough that you're not harming things by doing minimal work. If you work for a multi-thousand-person company with bureaucracy and redundancies all over the place, it's probably fine. If you work at a 15-person startup, where you not pulling your weight could mean the company is significantly more likely to fail, it'd be pretty shitty to stay in that situation and risk causing problems for your colleagues.
Also I hope you're working remotely now and can do fun/useful/productive non-work things with most of your day. If you had to sit in an office for 8 hours while pretending to look busy (but actually just goofing off on the internet), I don't think that's a good use of your time (being paid or otherwise), and I doubt it'd be great for your mental health, either.
To add one more thing: don't make life hard for your peers. If your intentional lack of productivity is making your teammates' lives harder, that's not cool. Don't be selfish at the expense of others.
