Looks sensible overall, but I think we need to change from "Organization" to "owner" and "User/Organization".

I started adding comments for things that need to change, but I think it's pretty straight forward to figure it out.

And a minor comment is that we generally use US spelling for public facing strings.

Looks good to me. We need to avoid merging until the related backend change is deployed.

Thanks - yep, it's why it's still in draft :D I'll test once the back-end changes are in and publish the PR if all is well.
