Adding a New Side-View
A Workspace Access plugin type can contribute a new side view to Oxygen XML Author. For example, the following plugin.xml descriptor file defines a new view ID called SampleWorkspaceAccessToolbarID: https://github.com/oxygenxml/sample-plugin-workspace-access/blob/master/plugin.xml.
Once the new view ID is declared, the Java code of the plugin can add content to the view using the pluginWorkspaceAccess.addViewComponentCustomizer API.
