Is there any way to get real data persistence in Figma Make without connecting an external backend (Supabase, Firebase, JSONBin, etc.)?

Hey everyone!

I know Figma Make has an official Supabase integration for this. My question: is there any native way to make user interactions (edits, additions, etc.) on a published app persist and be visible to every visitor — like a shared database, not just local/per-user storage  without connecting an external service like Supabase or Firebase?

Is this possible today within Figma Make, or is an external backend the only way to get shared/multi-user persistence? Thanks!
