Obtaining windows update (KBID) supersedence chain without WSUS

- When trying to use the MSRC API to obtain the update supersedence chain, I found that it does not contain "Cumulative Update Preview". Will the follow-up MSRC API include "Cumulative Update Preview" related updates?
- Try to view each update's supersedence chain from wsuscan2.cab, there are the following problems:
(1) According to the official description, the "c" folder contains Core data, the "E" folder contains Eula, the "L" folder contains Localized information, and the "X" folder contains Extended information.
May I only need to view the files in the "c" folder?
(2) In wsuscan2.cab, except querying the "UpdateIdentity UpdateID" of each update through the Microsoft Update Catalog website, is there any other way to convert it to KBID or Title?
EX:
UpdateIdentity UpdateID="5decae47-2169-4567-a1aa-fb1f630e9ecd"
Search through the Microsoft Update Catalog website, the corresponding Title="2021-05 Cumulative Update Preview for Windows 10 Version 1809 for x86-based Systems (KB5003217)"
Thanks for the assistance!
