The extension works as advertised. Simply highlight your selection, then right click or press pinned icon to copy highlighted links. Like almost all other similar extensions, it is missing a crucial function: Remove Duplicates. Currently, on some websites (youtube.com for example) if you highlight videos from the playlist or videos page and copy the links, you will get 3x to 4x the desired links due to duplication. A remove duplicates function would eliminate that issue and the extension would be 100%.
