Unfortunately, there is no straightforward way to report Outbound clicks in google analytics.
You will have to create a custom report for that in the analysis hub.
GA4 captures link clicks with the event name of "click"; In the click event, it also passes some additional parameters such as link_domain, link_id, link_url, link_classes, outbound (boolean), etc.
You need to register the required parameters as custom dimensions. In this case, I would recommend you to setup at least link_url as a custom dimension.
It will take up to 24 hours to show up in the GA4 reports & Analysis Hub. So, unfortunately, you have to wait.
Now you will need to create A custom report in The Analysis Hub.
