Hi all! I ran the Lightning Experience Configuration Converter for JavaScript buttons and I only have one button. However, it's on the Opportunity Line Item object, and I'm getting an error that says "OpportunityLineItem object isn't supported". Does that mean that this object has entirely disappeared in Lightning? How do I deal with this button conversion?

I thought I could create a Quick Action on the Opportunity Product object, but it's not even an option. Any ideas on another route I could go? The button sits on the Opportunity Product record and clones the existing record with pre-populated pricing and cost fields on an edit screen. Thanks for any ideas!
