Detecting the full URL of "external assets" of Android app?

One of the android games I play is a Unity-based game, but not all of the data seems to be downloaded into the phone. There are "external assets" that seems to be in an online server, and all the Process Hacker managed to detect is something that looks like this:
"0x503f40d0 (79): assets/furyu/externalassets/personal/characters/face/0001000000/textures/jz.png"
It does not give me the full HTTP URL. 
I tried checking if there original URL is declared elsewhere but I can't find anything.

Is there a way to tunnel this? Older emulators like Bluestacks 2 and 3 used to be able to connect to Chrome Inspect, but not anymore. Bluestacks 4 onwards and Nox cannot be inspected through Chrome inspect.

I've checked to see if this is actually a directory within the root folder, but it isn't. Assets that are downloaded into the device is in a "TEMP" directory, or in the form of Unity files that I needed to unpack with AssetStudio. There are no direct PNG files.
So is there an alternate way to detect the URL? They've hidden the base "http" directory somewhere, and Process Hacker was only able to see the sub-directories
