The docs state that any Site Member can approve; however, as a Collaborator role, I do not see the Reject / Approve buttons in the Deploy screen… Do I need to be an Owner? Can an Owner grant this permission to specific Collaborators?
Thanks so much for reaching out and welcome to the forums! Only Site Owners and Site Members can approve pull request deployments. Collaborators do not have this permission by default.
You will need to ask the site owner to manage your role in the site settings so you can be granted the ability to approve or reject a request.
