How to find decorationIds and specific origins?

[skillIssueSwe]

Hi,
I am currently working on a project similar to this one as a learning exercise and wanted to ask about how you guys were able to find the origin and the decorationId, that is used in the job_search functions queries. I want to be able to reliably update my application if LinkedIn changes endpoints similar to how you guys have done on this project. I left a comment on the file here highlighting the specific things I was wondering.

I did comb through the network feed, as well as sources from the job feed and job search pages, and found many origins and decorationIds but not the ones here, at least not on those pages. Any advice is super appreciated, thanks so much!
