If you don't like design, and you want to work as a professional in the software industry, then you really need to go deeper. Even if you happen to have a job right now doing "light" coding tasks with bits of JS, you'll be the first to go with the software industry goes off the rails.
I've seen this happen already after the dotcom crash. In fact, it happened to me. I was doing more or less what you are doing now, and once times got tough, I found it very hard to find decent work. I left the profession for a while (although I continued to do a bit of coding as part of my job), but when I came back I buckled down and learned to be an actual software developer, learning everything from low-level programming, to data structures and algorithms, to architecture. It was gradual, but I knew were I was going.
I happen to work in frontend dev now, but building actual web applications (and feel just as comfortable building applications on the desktop, or Android, both of which I've also done professionally). Now when the shit hits the fan, I'm fairly sure to keep my job, or find another one if needed.
Also, as you allude to the kind of skill you're talking about will be increasingly vulnerable to automation. But not just the "low-code" things. Also the HTML, CSS, and light JS things. And things that are "low-code" now will be virtually "nocode" in the future, capable of being done by any random office worker.
If you want to be a coder, then master coding. Or else go into design and master design. Either way, set your sites on mastering something, don't just play around the edges. It's a process, and a hard one at times, but I'm convinced that anyone can do it. If you're already enjoying working with HTML, CSS, and bits of JS, then you'll likely do just fine teaching yourself to be a full-fledged professional developer.
