Can remote team members whiteboard collaboratively & in real-time using the Miro power up?

[Matt Yurdana]

I'd like to have remote members whiteboard together in real-time. I've added the Miro power up, but when I've tested this, it seems others can't see the whiteboard I'm working on in a card. Do all members need a Miro account? Or is this something that can only happen in Business Class? Many thanks!
