Token source wrapper that refreshes expiring OAuth2 tokens through Pristine.OAuth2.
Options:
:inner_source- required wrapped token source as{module, keyword()}ormodule:provider- requiredPristine.OAuth2.Provider:context- Pristine context used for the refresh request:client_id- OAuth client id for the refresh request:client_secret- OAuth client secret for the refresh request:token_params- extra provider-specific refresh params:refresh_skew_seconds- refresh before expiry by this many seconds
The wrapper only attempts refresh when the current token has a real
expires_at value. If the provider returns a replacement refresh token, the
wrapper persists that rotated value back through the wrapped token source.
