Initially, the desired transaction failed @leveuf. But, as we can see in the comments, the LeoFinance team lead got right on the problems presented to them and I was able to complete the transaction later in the evening on the same day I wrote this post.
While not all of the tokens on Hive Engine can be traded on LeoDex, one of the benefits is simply the reduced price of transactions, as mentioned in the post. Given how it is somehow tied to Hive Engine anyway, it is the least expensive way to get the SWAP.HIVE tokens needed for doing any trades.
With family and ministry commitments now behind me for the moment, "back in" for a bit this evening to catch up.
God bless you @leveuf and yours in these difficult days!
