If you want to make a copy of your created template, follow the listed steps:
1. Go to the My Design tab from the home page.
2. Hover the cursor over the design you’d like to duplicate.
3. Click on … (three dots) on the thumbnail and select Duplicate option.
If you created copy from My Design, you'll find it under My Design option. If you did so from inside a folder, the copy will also be created in the same folder.
Rename the duplicated design to easily distinguish it from the original.
