Looks good to me, thanks!

This seems odd, @Danieladu @chon219 @joshgummersall is there a reason we don't have a central version of this test.schema hosted somewhere? (Like https://schemas.botframework.com/schemas/component/v1.0/component.schema)

Not blocking on this comment, just wondering if this can be tightened up. Especially since the JS SDK's AdaptiveDialog/Declarative parity is closer than it's ever been with the .NET SDK.
