Removing sharing, not deleting all shared layers

I need to know how to “UNSHARE” not delete. I still need the layer! Somehow I hit some shortcut by mistake, and now it’s shared everywhere adn I don’t want that, but there’s no option to NOT share it and return it to normal. Help!

If you control + click on the layer in the layer sidebar, under Layer Settings, uncheck “Shared Layer”. Do this on the canvas you want to keep the layer.

Can also do by selecting the layer and using the Edit -> Layers -> Layer Settings and uncheck “Shared Layer”
