You don't need date-fns*:

Temporal has a built-in add method on all its classes:
* Not really, see: https://date-fns.org/you-dont-need-date-fns
Example
```
// Add 10 days to 1 September 2014:
const result = addDays(new Date(2014, 8, 1), 10)
//=> Thu Sep 11 2014 00:00:00
```
Example
```
// Using Temporal:
// Add 10 days to 1 September 2014:
Temporal.PlainDate.from("2014-09-01").add({ days: 10 }).toString();
//=> "2014-09-11"
```
