Fix LinkedIn Extension Bug

My LinkedIn-focused Chrome extension fails to locate the “Message” button on a particular LinkedIn page, so any action that relies on that element never fires. Every other feature loads correctly; the issue is isolated to this single page view.

I need a developer who is comfortable debugging Chrome extensions, the LinkedIn DOM, and JavaScript/TypeScript content scripts. Please trace why the selector or logic that targets the “Message” button breaks on that page, then deliver a clean patch that restores normal behaviour without introducing regressions elsewhere.

When you respond, share a quick link or screenshot of past work fixing browser-extension or LinkedIn-automation bugs so I can gauge fit. Once we agree, I’ll give you the repo and reproduce steps; I can test your fix right away and merge as soon as the button is reliably detected again on that page.
