Praying in one accord

Acts 4.24 says in part, “they raised their voice to God with one accord and said…”

How did they do pray in one accord?

Did they all speak simultaneously?

If so, was the prayer written out beforehand?

Or did someone say a few words, and the others repeat it?

Or did Luke simply mean that one man uttered the prayer, and he spoke for all?

Or are there other options?
