+Sometimes you may need to add some custom metadata like build number or branch name to Selenium logs. Just add the following capability to your tests under `ggr:options`:
 
 .Type: map, format: "<key>": "<value>"

 labels: {"buildNumber": 122, "branch": "feature-XXX"}

 With this capability browser column will look like this:
