Hi. I'm new to Trello and the community.
I am currently using a Butler Power-Up Card Button to copy a card to another board and link the two copies. That link shows up in each card as an Attachment.

Later on I use another Card Button on the "original card" to finish my process. As part of that, I archive that copied card on the other board, BUT, I also want to remove the link between the two cards. I've tried several combinations but I haven't figured it out yet.
This part of the command is being acted on the "found" card (the one that was copied to another board and linked):
I tried remove link using these variables: {cardlink} or {triggercardlink} or {triggercardid}. But none of these remove the link between the two cards.
Anyone know how to do this? Thanks.
