⚠️ The command "overrides" previous data, so if one node is using `ReceiveData`, but before the receive call the other node uses two consecutive `SendData`s, the receiving end will only get the last stream.
⚠️ After calling this command, the host sends the data automatically. Guests only **schedule** the data transfer, but they don't do it until the host sends something.
