Lease buyout through MFS

On the MFS app it gives me the option to buyout my lease. I was just wondering what that would look like, if anyone has experience doing this. I’m not planning to finance it I’m looking to pay it off in one shot. Right now it’s showing my buyout to be roughly 23,000 including sales tax (23’ cx5 carbon). Would I not have to visit the dealership? I’d much rather avoid the dealership if possible lol
