Windows 10: Question about Microsoft Update Catalog informaiton

I have a question regarding patch information in Microsoft Update Catalog site. For example KB4535680: Security update for Secure Boot DBX: January 12, 2021 - Microsoft Support , and in this article I can see KB45356803 has been superseded by KB5012170, but I cannot find similar replacement information in Catalog site for KB5012170. So the question is whether such replacement information can be found on Catalog site or will it be possible to update the information on the Catalog site ?KB5012170: Security update for Secure Boot DBX - Microsoft SupportMicrosoft Update Catalog
