Opera GX Cursor Mod Creation Issues

Hello! I am trying to create a cursor mod for OperaGX, but I keep running into this issue in the attached screenshots, and cannot seem to fix it in my manifest.json.
I copy pasted a default "web_accessible_resources" section from a windows forum and entered my custom data, but it seems to not be working.
Originally, since there was no info online that I could find on how to start creating a cursor mod, I just copied the files of a cursor mod already on the Opera GX mods section. And that one did not even have a "web_accessible_resources" section, so I am lost.
Further, the mod came with an already generated "key" and "hash" and "parent_hash", idk if I need to change those, or if they are a none issue.
Any direction on what I am doing wrong would be appreciated!

For anyone who has similar issues... After a couple days of messing around;
I am guessing manifest_version 2 requires stricter associations.
With my last screenshot as reference:
Delete the entire "web_accesible_resources" block.
Delete the entire "key" line.
Change the "manifest_version" to "3,"Loaded fine.
This is probably a janky solution? idk if it will cause any issues elsewhere.

I don't think I've ever seen a mod that uses manifest v2. They should all be v3.

@burnout426 Thank you for the info! I was confused about the exact usage of the manifest versions. I'm pretty new to this.

But switching to 3 did fix the issue!
