I accidentally switched Genshin Impact to window mode. How to switch back to full screen?

Genshin Impact was accidentally switched to window mode, so players can change it to full screen mode in the game video settings. In the game, after the player's adventure level reaches 16, the multiplayer option will be turned on, and players in the same area can connect online, and up to 4 people can connect online.

Online players will enter the host world, and the other three players can get all kinds of materials in the host world, and they can also challenge the secret world, but they can't interact with NPC. If the player is engaged in a main line task or a special task, it will not be possible to play multiplayer games.
