allow-nether=true # Whether to enable the Nether world (if closed, the Nether world will not be generated)

max-world-size=29999984 # Set the maximum radius value of the world boundary, in blocks. The world boundary can be set larger through successfully executed commands, # but it will not exceed the maximum block limit set here. If the set max-world-size exceeds the default size, it will have no effect.

The method is to paste the code in generator-settings
