Feature request: provide an expiration timestamp for public tokens inside LinkSuccess

[cmathew]

the documentation is clear that these tokens last 30 minutes. That said, it'd be nice to check for expiration without relying on constants.

Thanks for the feature request! To be honest the public token is designed to be used immediately after you get it, so the 30-minute expiration shouldn't really be something you encounter IRL -- it's really just a security backstop. If you are running into a use case where you're seeing public tokens expire, let me know, but I suspect it might point to some kind of design issue in how you're using them?
