Player wallet will be generated upon login to the Xternity wallet,
Any NFT that will be minted to this player before wallet created will go to status PENDING_WALLET
Once player's wallet created all NFTs (up to game's players free mint limit) will be minted automatically
In the sandbox env only we can create a wallet by this API for tests only, no one will get this test wallet keys, yet its on chain and can be tested in 3rd parties like OpenSea and Scanners
