Man can in Minecraft Bedrock for Android / Win10 connect locally with each other in which one is in the same Wi-Fi network and then play together in a self-made map. Does this work in the Bedrock Edition for Nintendo Switch?
You can also join online "afterwards"
There's the catch. I do not have Wi-Fi with which I can play online. That's why local network.
Oh. Yes, I do not know but would have to go to a console
