I think you’re looking for `card-contents-base.js.es6`, which defines a series of events which point to the `_show` method.

```plaintext
# card-contents-base.js.es6#103
$("#main-outlet").on(clickDataExpand, `[data-${id}]`, e => {});

$("#main-outlet").on(clickMention, `a.${triggeringLinkClass}`, e => {});

this.appEvents.on(previewClickEvent, $target => {});

```

```plaintext
# card-contents-base.js.es6#20
_show(username, $target) {}

```
