Normally apps can’t cross authenticate like that because they don’t have the ability to talk to each other in a standard way that’s also verifiable and secure. Teams could have a way to share your auth to something else, but it’s much more difficult for it to know that the thing asking for access actually is something that’s supposed to be able to do so.
OneDrive is built in to Windows, so it’s able to use the authentication you use to log into the computer to talk to the Microsoft servers. (Essentially, there’s like a million steps and layers of indirection).
