Where to put my .obb file?

Hello. This may seem like a silly question but where to I put the obb file. This is my first time exporting a game using split application binary and I just can figure out where to put the file. I tried sdcard/Android/data/[packagename] and sdcard/Android/data/[packagename]/files and sdcard/Android/obb/[packagename] and I just can’t seem to figure out why my next scene isn’t loading. I checked if I referenced the correct scene index and I didn’t rename the obb file after export. I also have various games on my device that use obb files and I tried using their file path style with my game but still no luck. Someone please help.

Ok I figured it out. I had to rename the obb file using [main|patch].[expansion-version].[package-name].obb and then place it in sdcard/Android/obb/[package-name]
