As I understand the thread, the water pump has a manufacture date stamp of 2022 indicating it has been fitted after that date. It is inconceivable that a Volvo dealer would change a pump and not the belt at the same time - so the belt will be relatively new. Given that the car has not been used for twelve months and the cam sprokets are rusty, the belt will be 'set' around the pulleys through standing, I would change the belt 'just in case'.
