I’ve integrated a number of modules using javascript without going through the Vue component process. I have some speedruns and tutorials on key parts of that process on the statechange youtube channel: State Change - YouTube. It doesn’t have to be super-complicated, but it is work, and its definitely low-code rather than no-code.
If you want more help than that, we have tools and office hours to make these kinds of hardest 5% projects easier too at State Change.
