If the Catholic Church approve a private revelation as worthy is the Church also obliged to follow the messages and requests?

I'm referring to the Fatima visions as they were approved by the Church. In these visions, virgin Mary asks for the consecration of Russia. Is the Church obligated to do it or can the Church(pope) say this is a private revelation and we as the church don't submit to its authority? Something like if God wants it the Holy Spirit would lead the Pope and the bishop the "standard" way as we know it from the tradition, similarly when they decide dogmas.
