Tracking Email Engagement in Smartlead Campaigns

Anyone using Clay with Smartlead - is there a way to get Status in Clay using the Smartlead API? I have paused my SL campaign and want to filter leads to see who has received Email 1 and who hasn't started yet. I've tried 'Lead status' in Clay integration but it just says 'Lead Not Active in Campaign Yet' for all leads, even those who have received an Email 1
