Can't get web item to appear at atl.jira.view.issue.right.context

Hi,

I am trying to get a link that opens a dialogue in the right hand issue context. I can get a web panel to work just fine, but a web item refuses to show. Does this location support web items/am I missing something?

This is my atlassian-connect.json the web panel correctly adds a P4Jira X field to the right context, but I cannot get the web item to show up.

{
   "key":"p4cjira",
   "name":"p4cjira",
   "description":"Perforce <=> Jira bridge",
   "baseUrl":"{{localBaseUrl}}",
   "authentication":{
      "type":"jwt"
   },
   "lifecycle":{
      "installed":"/installed"
   },
   "scopes":[
      "READ"
   ],
   "modules":{
      "dialogs":[
         {
            "url":"/p4jira?issueId={issue.key}",
            "options":{
               "size":"fullscreen",
               "header":{
                  "value":"P4Jira Header"
               }
            },
            "key":"p4jira-dialog"
         }
      ],
      "webItems":[
         {
            "key":"p4jira-link2",
            "name":{
               "value":"P4Jira X2"
            },
            "location":"atl.jira.view.issue.right.context",
            "weight":10,
            "target":{
               "type":"dialogmodule",
               "options":{
                  "key":"p4jira-dialog"
               }
            }
         }
      ],
      "webPanels":[
         {
            "key":"p4jira-issue-left-panel",
            "location":"atl.jira.view.issue.left.context",
            "weight":10,
            "name":{
               "value":"P4Jira"
            },
            "url":"/p4jira?issueId={issue.key}"
         }
      ]
   }
}

I am trying to do the same as the inbuilt DVCS link/dialog like the highlighted if anyone has an idea:

Cheers,

Brett
