microsoft flight simulator on a cloud service like x cloud/stadia/playkey/nvidia geforce now

hello, 

i have a imac 2017, and was hoping that xbox series x would have flight simulator 2020 on release date. 

now i just sold my xbox series x unopened and still very tempted to try flight simulator 2020 on iMac with an cloud service. 

i just tried yesterday the playkey.net russian service, and it was pretty good but not decent. 

i want to buy flight simulator on the microsoft store - not steam (so it would probably be available at xbox series x when it will be launched later next year).

nvidia geforce now have only steam, but not microsoft store as a game library. i also checked out shadow cloud service - but you have to wait a couple of months before the computer that they build for you will be available for cloud service. 

my main question is : is there any way to play ms flight simulator on a mac without bootcamp/parallel desktop on a good cloud service that gives a high/ultra settings?? would prefer to buy on microsoft store directly. i don't know how x cloud service are here in sweden.
