I want to know the answer to the following question:
What had Aleksei and Filaret been up to at the time of the protest?
All the background I'm provided with is that "On October 28 UAOC faithful, supported by Ukrainian Catholics, demonstrated near St. Sophia’s Cathedral as newly elected Russian Orthodox Church Patriarch Aleksei and Metropolitan Filaret celebrated liturgy at the shrine.". Is that enough to answer the question?
Answer: yes
