Missing information on Realtime participant token expiration

[KazimirPodolski]

Existing documentation URL(s)

https://developers.cloudflare.com/realtime/realtimekit/concepts/participant/#participant-tokens

What changes are you suggesting?

The docs state that participant tokens expire, but doesn't say how it's reflected in the API. API field? Error response? Something else?

Please clarify how a developer can find out a token has expired.
