The options listed depend on the type of item you’re sharing. For example, when an image is selected, you can choose to set it as your desktop picture. To customise the Share menu in Extensions preferences, choose More.

.On the left, click Share Menu, then select the sharing extensions you want to include in the Share menu; deselect those you don’t want included.
