In Wolvenkit, open the file base\worlds\03_night_city\_compiled\default\blocks\all.streamingblock
Switch to the second tab "All Sector Preview"
In the panel to the right, enter the coordinates that you copied from the game in step 2
Click "Search for Coordinate"
Optional: Zoom in
You can double-click on the red text to load the corresponding streamingsector file into the streamingblock's preview!

Method 2: Following the meshes
If you know a mesh that's used inside the location, you can right-click the mesh file inside Wolvenkit's asset browser and use "Find files using this".
You might want to consider using a unique mesh rather than a standard cup or bottle.
Method 3: Via script
Go here for PL (old link) and either use the script in your webbrowser (recommended) or download the script locally to run it with Python.
When running from browser:
When running locally:
The script requires you to have a local json export of all.streamingblock somewhere.
Change line 11 to the absolute path of your json (remember the double slashes):
Now, run the script via Python. It'll give you a list of interior/exterior sector files together with the distance from your coordinates.
The blocks at the bottom can be used to generate a streamingblock json file for just the results, which can be imported to wolvenkit to preview them as per Method 1. if running the script locally you will need to download the sectors.streamingblock file from the github and edit the templatepath variable to point at it.
Change the x, y and z coordinate to the coordinates that you found via CET
