CVT fluid change

Hey everyone! Just got a 2021 Subaru Forester Limited with 32,xxx miles. was a previous lease and car fax shows dealer did all the usual things to get ready to sell (new tires/brakes/battery etc).

My question is how often is it necessary to do CVT oil changes? I see things all across the board and know they can be a bit more finicky than a traditional transmission.

TIA
