online generator missing --config option

[ghost]

there is a --config in cli which said that
-c, --config Path to json configuration file. File content
should be in a json format {"optionKey":"
optionValue", "optionKey1":"optionValue1"...}
Supported options can be different for each
language. Run config-help -l {lang} command for
language specific config options.
but online generator https://generator3.swagger.io/index.html api /generate have no this config option
