Resolved How do unity know the catalog file name?

How do unity know the catalog file name? The CheckForCatalogUpdates() doesn't accept any URL.
Everytime I do a build it create hash and json file with different file name because of the time stamp part.

Example:
catalog_2022.03.30.14.55.39.hash
catalog_2022.03.30.14.55.39.json

Is the filename stored some where everytime I do a build so that Unity know what file name to use on the file server?

What if I only want to update content but user don't actually need to update the application?

Do I rename the hash and json to last timestamp so that it will fetch the new file list correctly?

Update:
I realized that when you "update" a build instead of "create a new build", the catalog file name will not change. So the file name is probably hardcoded when you build the game.

 

so we basically have to hardcode or store the catalog name on a server?
speaking here for a project that builds addressables in another project.

isn't there way to give unity a directory URL and to figure out the latest catalog automatically? at least for initial iterations, this would be incredibly useful. setting up a server just for this seems overkill
