Are there any new methods on pulling expired options data?

Hello! I am currently utilizing an updated version of script functions posted below to obtain valid RIC codes for expired options data.

Since this method is much more costly compared to pulling active options from existing chain codes, do any new techniques exist for finding expired options RIC codes? I will appreciate any feedback on the matter.
