Auto delete SharePoint News posts after a certain period

Hello Everyone,

I was asked by a client to set a "Retention" period of 3 years for News posts in a SharePoint site. The idea is the News posts older than 3 yeas will be automatically deleted. I can't find a way to do this automatically. Does anyone here know if this is possible and how to achieve it?

Thank you all in advance and have a wonderful day 😉
