What were the deeds the church in Ephesus had done at first, to which Jesus called for a return?

"Return to your first love" is a Christian cliche, applied to congregations by pastors; but I have never heard specifics given that were in context. So, what had the believers in Ephesus done up to Jesus's visit with John that they had forsaken? And did they repent?
