Cannot Add Alerts for YouTube Jewels / Rubíes (Vertical Stream Gifts)

I’m streaming on YouTube and viewers send jewels/rubíes (the gift system used in vertical livestreams). However, StreamElements does not trigger any alerts for these gifts — they don’t appear in the Activity Feed, and I cannot set up any alert for them.

Super Chats, Super Stickers, and Memberships work normally, but YouTube jewels do not show up at all.

I want to confirm whether StreamElements supports jewels/rubíes or if this feature is not available yet. If it’s not supported, is it planned for future updates?
