Oracle Integration Cloud - How do I create a date var and add a year?

Hi folks

 

Hoping someone can show me how to do this as I'm losing my marbles trying thing after thing and getting errors every time.

 

If I output  string(fn:current-date()) I get 2021-08-17T15:23:52.198Z

 

So, I thought to create a date I would be able to define a variable in the same format as that, and then use +xsd:dayTimeDuration("P1Y") to add a year to it, but no, that will not work.

 

In the variable creation window :

I've tried xsd:dateTime('2021-08-17T15:23:52.198Z')+xsd:dayTimeDuration("P1Y") and this errors.
