It was a pleasure to test for you!
To copy: go to your shop and there should be 3 dots (at least on mobil this is on the top right) click on it, and a tiny pop up will appear where you just click on the copy icon!
Edit to add picture! This is for your shop, but same goes for each pattern!
It was a delight testing for you also you should use the selfee link. To get the selfee link, go into your shop and click on the pattern then click this symbol and copy. It can help make fees less
