LinkedIn connect-with-note modal lives in #interop-outlet shadow DOM

The connect-with-note textarea is NOT in the main document DOM - document.querySelectorAll("textarea") returns zero results when the modal is visible. LinkedIn renders the modal inside a shadow root attached to a #interop-outlet element. To reach the textarea: const root = document.querySelector("#interop-outlet").shadowRoot; const ta = root.querySelector("textarea#custom-message"). React also won't pick up a direct ta.value = X assignment - you must use the native HTMLTextAreaElement value setter and dispatch input + change events with composed: true: const setter = Object.getOwnPropertyDescriptor(HTMLTextAreaElement.prototype, "value").set; setter.call(ta, msg); ta.dispatchEvent(new Event("input", {bubbles: true, composed: true})). Separately: accounts with ~5K+ followers (Creator profiles) hide the direct Connect button - you have to click the ... menu first to reveal Connect.
