Should a Church call out False Prophets who claim to speak with God's word?

This question isn't about a specific situation but was brought on when I read about a few "prophecies" in the US claiming that Trump would win the 2020 election - a prophecy we now know to be false. They claim that God is telling them these things - there are many people that follow these speakers and are led astray by them. Is there any responsibility on others within a Church (of any denomination) to denounce these people using the Lord's name to further their own goals? i.e. if a Catholic Priest were to make such claims and so publicly should the Pope step in to separate this view from that of the Catholic faith to minimise the damage done to that congregation?
