In my experience, "Low Code" is almost always weasel-wording. It's used to describe products that try to be "No Code", but fall short. It's a way of making excuses for everything you can't do, because you can get a "real programmer" to come in and paper over the cracks. Actually writing this code is rarely a pleasant experience, and the learning curve is a cliff that goes straight from "flowchart" to "writing React" (or worse).
As other replies have pointed out, the really successful tools are like Excel: They have a real programming language at the heart of them, and they don't try to hide it away.
Disclaimer: I founded and run something you could call a "Low-Code web environment" (https://anvil.works) - but I prefer "Visual Basic for the Web" (or "Web Apps With Nothing but Python"). We built it around the idea that writing code is inevitable - indeed, it's the best way to tell a computer what to do. So don't try to hide it - make it a first-class experience!
