Looks good to me, I don't love the quote / spacing changes but I'll let the @eshaben's regulators team decide on that

[eshaben]

I don't see any spacing issues, but we can rollback the double quotes to single quotes. I don't have a strong opinion on this

[aljosamakevic]

Noted. I've changed the double quotes back to single quotes and edited my prettier config so this doesn't happen again
