Link Spotter can be removed from a channel the same way like any other common MS Teams app.
Simply navigate to the Teams channel where you added the app and open the tab. After that you will be able to open the context menu of the tab by clicking on the arrow near your tabs name.

A dialog will be opened where you are able to choose whether application data of that channel shall be deleted (per default data will be deleted).
The option to delete app data is disabled when you have added multiple instances to the same channel.
Approving the dialog will remove Link Spotter from the channel.
