Qualtrics.SurveyEngine.addOnReady(function () {
	const quest = this;
	const qc = quest.getQuestionContainer();
	const inputBox = qc.querySelector(".InputText");

	inputBox.oninput = function (ev) {
		const text = ev.target.value;
		const last8 = text.slice(text.length - 8);
		Qualtrics.SurveyEngine.setEmbeddedData("last8", last8);
	};
});

Change the last8 line to:
