Unable to generate content update webhook event in Confluence cloud

Hi,
I have created Confluence webhook using confluence Framework and it works fine and gives me updates on each change made on confluence but I am unable to generate a ‘content_updated’ webhook event.
Even after updating the content of the page content_updated webhook event is not triggered.
Can you please help me with the way to generate content_updated webhook event

Regards
