Cómo verificar si el objeto existe y luego actualizar; de lo contrario, inserte un nuevo objeto usando mongoose y node js express

Los datos agregados están funcionando perfectamente. Quiero mi solución de declaración if.

 const user = await Data.findOne({ email: req.body.email }).select("email").lean(); // here i want to update if (user) { console.log("data updated"); } else { const dataa = new Data(req.body) let savedData = await dataa.save().then((resp) => console.log(resp)) console.log(savedData, "after save"); }
