How do I retrieve text messages that have been deleted on my iPhone 13?

How do I retrieve a text that the sender somehow deleted from my iPhone 13 because several texts have been deleted & I need them in Court ?

I've heard this could be done but didn't think it was true until a contractor deleted texts he had texted me that I desperately need. The Texts he sent have Disappeared.

How can I get his texts back that he deleted somehow from my iPhone using his iPhone ?
