Add show workflow UI Action in ServiceNow for Global and scoped applications

For Global Application use the following script

onclik: showWorkflowContext()

condition: !current.isNewRecord() && (new Workflow().hasWorkflow(current))

function showWorkflowContext() {

   var id = g_form.getUniqueValue().toString();

   var url = new GlideURL('context_workflow.do');

   url.addParam('sysparm_stack', 'no');

   url.addParam('sysparm_table', g_form.getTableName());

   url.addParam('sysparm_document', id);

   g_navigation.open(url.getURL(), "_blank")

}

For Scoped Application use the following script

onclik: showWorkflowContext()

condition: !current.isNewRecord() && (new global.Workflow().hasWorkflow(current))

Script: Same as above
