It is common for lay people to give “reflections” during the homily time of the Mass. The priest would either do a quick homily and introduce the special lay person (often someone leading some retreat in the near future).
This seems like a nothingburger.
Sure, that happens all the time, wrongly so. That is not proper or permitted in the mass, and not because the “special person” is a woman, but because only the ordained may give a homily.
I have often seen a guest speak at the END of mass or afterward at the coffee hour; that is what priests allow who obey the Church’s definition of their role.
If you are ignorant of liturgical rubrics or practice, don’t blame me for telling you what they are.
