How to tag umap(s) with AssetRegistrySearchable?

Hi!

I have some different maps that the player should be able to choose from. All the maps can have different settings that must be known to display accurate information to the user before loading the maps into memory.
I found How to tag umap(s) with AssetRegistrySearchable? - World Creation - Unreal Engine Forums I still can’t understand how to do it. Can anybody help?
