@pujaPatil169 is attempting to deploy a commit to the Piyush Garg's projects Team on Vercel.

A member of the Team first needs to authorize it.

I’m just a contributor submitting a pull request and not involved in the deployment process.

I noticed the "Vercel — Authorization required to deploy" check failed. Since I don’t have a Vercel account or permissions to deploy, I’m not sure why this is showing up.

Could you clarify why I’m seeing this authorization error for a pull request? Will I need to create a Vercel account for every contribution I make, or is this only for the repository owner?
