I'm creating an Opera GX Mod using Schema v2.

My mod works correctly when loaded unpacked, including the splash_screen payload. However, when I try to publish/update the same mod on GX Store, the upload is rejected with:

"Mod type restricted"

If I remove the splash_screen section from the manifest, the mod uploads successfully.

The splash screen itself works correctly locally, so I don't think the problem is with the MP4 file or the manifest structure.

Could you please clarify whether splash_screen requires special permission for community-created GX Mods, and if so, how can I request that permission?

Mod name: SUPXR's TYPE

Thank you!
