Documentation is missing which plug-in points are available in cockpit. A simple list or table might do for the first step.

by plug-In points I mean these view providers, e.g.:

ViewsProvider.registerDefaultView('cockpit.processInstance.instanceDetails',

{ id: 'linked-process-instances-tab', label: 'Process Instances related via Collaboration', url: 'plugin://bpmn-collaboration/static/app/linked-process-instance-table.html', controller: 'BpmnCollaborationController', priority: 12 }

);
