How can I revive players who have died in Minecraft without having to respawn?

I would like to recreate bedwars in Minecraft, but I don't know how I can make it so that when you die, you respawn immediately without the message whether you want to respawn. I would like to do this with a command block.

In theory, I think you can set that somewhere in the settings. But then everyone would have to stop. But you can probably change the settings via the cmd block.

Unfortunately only works with a plugin.

With a plugin. Either look for one or code yourself.
