How to enable this extension

Hi there!

Thanks for your query.

Which extension you are talking about, please?

Did you mean Joomla article details page? If yes, then you can find some options within the Global configuration of articles. Here are screenshots for your ease:

If you mean 'hits' with 'public view':

OUtput will be like this for Helix Ultimate: https://prnt.sc/-RX6vNNLeAS7

Print icon was available in Joomla 3 but Joomla 4 doesn't have the print icon/feature anymore within article details page as per my knowledge.

Best Regards
