It is suggested to only charge at 1C, so in this case is would be 4.6A. The CC/CV charging profile raises the charging current to the configured charge current, holds it there until the pack reaches 4.2 v (for 1s), then holds the voltage constant and slowly drops the current until the battery is "full". This usually happens when the current is approximately 0.10 A. It takes a significant amount of time for the current to drop to 0.10 A after the pack reaches the max voltage. As long as you have the time, let it charge all the way.
