onFinishCommand is not a function

[Baker68]

code :

yargs(hideBin(process.argv))
  .parserConfiguration({
    'unknown-options-as-args': true,
  })
  .command(commands)
  .demandCommand(1)
  .completion('completion')
  .strict()
  .help()
  .wrap(120)
  .middleware(middleware)
  .fail((msg: string, err: Error, yargs: Argv) => {
    yargs.showHelp();
  })
  .onFinishCommand((success) => {
    console.log(success);
  })
  .scriptName('kit')
  .showHelpOnFail(true, 'Sorry, we could not figure out what you want.')
  .version('2.0')
  .epilogue('Epilogue test').argv;

If I remove the onFinishCommand call, it works just fine.
Here is the full error message :

onFinishCommand was removed, PR which removed it: #1823

@Karizma , OK.
I can still make use of .fail() in conjunction with await to check if all commands have been successfully executed.
Thanks for your time.

onFinishCommand is still included in the latest version of @types/yargs. If it's not included in the JavaScript, shouldn't it be removed from the type declarations too?
