API similar to AvatarEditorService:GetInventoryAsync, but for loading a users favourited items, would require PromptAllowInventoryReadAccess to be in line with other AvatarEditorService APIs.
Would remove developers need to access v1/favorites/users/%d/favorites/%d/assets?limit=100 api via a proxy, this api is heavily rate limited and there is no api for loading favourited bundles (without authentication)
This would allow catalog games with built in favourite systems to be able to sync items players have favourited on roblox.
