According to Pentecostals, when were names added to the Book of Life?

According to Pentecostals, are names added to the Book of Life anywhere in the Bible (after Creation)? I see only examples of names remaining in or being wiped out. I don’t see names being added. >“The one who conquers will be clothed thus in white garments, and **I will never blot his name out of the book of life**. I will confess his name before my Father and before his angels.” ‭‭Revelation‬ ‭3:5‬ ‭ESV‬‬ In order to never be blotted out it’s implied you were already written in. When was it written in? What is the Pentecostal Charismatic view?
