No, it wasn’t. The Prophet’s responsibility was only to deliver the Message of Allah. Guidance comes only from Allah in accordance with the worth of every person.
(You surely cannot guide whoever you like ˹O Prophet˺, but it is Allah Who guides whoever He wills, and He knows best who are ˹fit to be˺ guided.) Al-Qasas 28:56
(You are not responsible for people’s guidance ˹O Prophet˺—it is Allah Who guides whoever He volitions.) Al-Baqara 2:272
