How to prompt all answers but one in a matrix table

Please try this:

Qualtrics.SurveyEngine.addOnReady(function () {
	const quest = this;
	const qc = quest.getQuestionContainer();

	const allRows = Array.from(qc.querySelectorAll("tr.ChoiceRow"));
	const optionRows = allRows.filter((row) => !row.querySelector(".InputText"));

	const holder = document.querySelector(".Skin");
	function rrHandler(mutationsList) {
		mutationsList.forEach(() => {
			const rr = document.querySelector(".RequestResponse");
			if (rr) {
				rr.classList.remove("shown");
				const allChecked = optionRows.all((row) => !!row.querySelector(".q-checked"));
				if (allChecked) {
					// Don't show request response options if all rows without without input box have answers
					const allButtons = holder.querySelectorAll(".ErrorButtons button");
					allButtons[0].click();
				} else {
					// Show request response options if there are some unanswered rows
					rr.classList.add("shown");
				}
			}
		});
	}

	const observer = new MutationObserver(rrHandler);
	observer.observe(holder, { childList: true });

	// Hide the request response options initially
	document.body.insertAdjacentHTML("beforeend", "<style>.RequestResponse{opacity: 0;}.RequestResponse.shown{opacity: 1;}</style>");
});

It works! Thank you so much, this is great! 

I just tried my whole survey. Is it possible that the code messes with other questions? I receive no prompt for other questions any more even though I activated it in the requirements.
