How can I change git branch for deployment in github

Howdy, folks!

I put my project out there with the main branch on Vercel for the real deal, the production site. But now I’m lookin’ to send it up again with the dev branch instead, so I can test things out on a staging spot over on Vercel. I got a feelin’ this used to work in an older version of Vercel, but I can’t seem to find that path no more. How might I go about this? I’d be much obliged for your wisdom.

Thank you, friends.
