What is your opinion on the book "Izhār al-Ḥaqq," and is there anything that would prevent a beginner student of knowledge from reading it?

The book "Izhar al-Haqq" (The Manifestation of Truth) by Rahmatullah al-Hindi is a beneficial book in refuting Christians. It proves the falsehood of the Trinity and the divinity of Jesus, demonstrates the miraculous nature of the Quran, the authenticity of the Hadith, and the prophethood of Muhammad (peace be upon him), and refutes the specious arguments of priests. It is useful for those who invite the People of the Book to Islam. However, for a beginner who is not specialized in inviting the People of the Book, it may be unsuitable because it compiles information about the Muslim creed, and detailed information about Christian beliefs and their refutation. Ignorance of the latter does not harm someone who is not engaged in refuting them. It is more appropriate for the beginner student to focus on what they are studying.
