  <Divider
    title="Title" // Title of the divider.
    dividerChar="=" // Character used for the divider line (instead of '-').
    dividerColor="red" // Color of the divider (red).
    width={40} // Width of the divider line.
  />

I am also experiencing this issue, the underlying problem is that the typescript configuration compiles the code for React 18, and react-jsx, and not everyone has this exact environment

The very simple solution is to export the files from the src/ directory, so that we can import directly from src and bypass the typescript compiler entirely
