How to stretch/warp the a vocal line to line up with another vocal line in Cubase?

Hi, I use Cubase 11 Elements and I’m experimenting with vocal doubling on my lead vocals. I have 2 separate takes of the lead vocals, each on different audio tracks, and I blend them together to create the doubling effect. However somebody told me that I need to stretch/warp the doubled vocal to line it up with the lead vocal take, otherwise it could be a bit noticeable, so it possible to do this in Cubase? What functions do I use? Thanks.
