Are there any Catholic Church writings or doctrines describing the important role of the Blessed Virgin Mary at the Upper Room?

In the Book of Acts chapter 1, the name of Mary is only mention in one verse. >All these devoted themselves with one accord to prayer, together with some women, and Mary the mother of Jesus, and his brothers.-Acts1:14 Is there any Early Church Fathers, Church Fathers, Theologians, Saints or Catholic Church teachings describing the role of the Blessed Virgin Mary at the Upper Room? We know that the Catholic Church proclaimed Mary as the "Mother of the Church". Mary plays an important role in giving birth to Jesus Christ, the Head of the Church. The Church is the Body of Christ. It follows that, if Mary gave birth to the Head of the Church, and to become the Mother of the Church, She must also give birth to the Church, the Body of Christ. We can also see, that in Mary's presence, in Her visitation to Elizabeth, at Her "greetings", John leaped and Elizabeth were filled with the Holy Spirit. **Is there any Catholic Church writings or doctrines describing the important role of the Blessed Virgin Mary at the Upper Room?**
