Get Negotiation Status using EL Expression

Hi.

I have a request from the business area to show or hide the button to publish the RFQ according to some conditions.

I did some research and didn't find any expression to get the negotiation status.

I found this expression on the RFQ page #{bindings.NegApprovalStatus.inputValue == 'APPROVED_NOT_PUBLISHED'}, based on it, I tried some others.

#{bindings.NegApprovalStatus.inputValue == 'CLOSED'}
#{bindings.NegStatus.inputValue == 'DRAFT'}
#{bindings.NegotiationStatusCode.inputValue == 'DRAFT'}
#{bindings.AuctionStatus.inputValue == 'DRAFT'}

All expressions returned false.

I got the status value using REST /fscmRestApi/resources/11.13.18.05/negotiationStatusesLOV

Any tips?

Thanks
