Hey! I just solved this issue.

Turns out react-xml-viewer uses modern JavaScript features like the nullish coalescing operator (??) and optional chaining (?.), which older browsers don't support without transpilation.

To fix it, you need to add these Babel plugins:

@babel/plugin-transform-nullish-coalescing-operator @babel/plugin-transform-optional-chaining

If you're still having trouble, just share your Webpack and Babel configs, and we'll figure it out together!
