Fathers Iphone 12 stolen

My fathers Iphone 12 got stolen on 7th April 2024. We put his Iphone on lost mode immediately with a lost display message through the find my phone section. We have also registered a police complaint. On 22nd May he got a phishing message saying his Iphone was found and can be tracked by clicking on the link & entering apple id and password. Unknowingly he got trapped by the message and gave away his apple Id and password. I know it was a mistake to give away the apple Id and password, but are there still any ways by which we can still be hopeful to find his Iphone?

Note: His phone has a pass code lock and face Id lock. We are still in control of the apple Id and have changed the password immediately on 22nd May itself. The device is still showing in devices/ find my section but with a message that it will be removed after 21st June.
