Is it obligatory for one who has repented from lying to inform the person to whom they lied?

To repent from a sin related to the rights of another human being, in addition to the general conditions of repentance, it is required to clear oneself with the owner of the right. This is the view of the Imams Malik, Abu Hanifa, Shafi'i, Ghazali, Qurtubi, and Nawawi, based on the hadith: "Whoever has wronged his brother... let him seek his forgiveness."

As for the other opinion, chosen by Ibn Taymiyyah and preferred by Ibn Al-Qayyim and As-Saffarini as the view of the majority, it distinguishes between rights that can be fulfilled, such as money (which must be returned to its owner), and rights that cannot be fulfilled, such as backbiting and lying (for which prayer, seeking forgiveness, and mentioning the person positively are sufficient). This latter opinion is the more probable one, based on the premise that informing the owner of the right in the second case might cause harm, and because financial rights differ from others in their utility. In the case of lying, there is no obligation to inform the person, but rather to repent to Allah and treat well those who were lied about.
