Hi Team,

We are trying to use Unifaun shipment options in our app and when we try to use that checkout option, the shipment option order in the dropdown changed when compared to Unifaun shipment option. Please advise us to proivde a proper way to put the shipment options in same order as in Unifaun.

The dropdown in Unifaun dashboard shows in IMAGE LINK BELOW.
