No 'folder name' option for storage retrieval

[Jinfra]

1. My goal: selecting all files in a certain map/folder
2. Issue: I do not have the 'folder name' option
3. Steps I've taken to troubleshoot: tried using the transformer to filter out irrelevant files, but does not work + not performant for scaling. Found this thread but afaik I do not have any beta functions turned on: Dynamic Folder Name in Storage Query parsing error - #3 by bobthebear. For now I've filtered it in the component itself, but this is really not performant + this is even harder and hackier for mobile.
