Sea of Thieves crossplay?

- in Xbox

My friends have Sea of thieves on steam. I would like to buy it from MMOGA for xbox / windows10 (microsoft store).
If I buy it from MMOGA at the Microsoft store and then, can I play with my friends at no extra cost?

Either way, an Xbox Live account is required. So no matter where you buy it, you play on the same server.
