Why multiple commands in yargs are not working?

Question

I am working on a CLI Project, where the user has to login before using any of its other commands. Below are the commands that the user will interact with.

1. oms login -u username -p -a auth_url
2. oms get -u url

When I'm trying to see the help for oms login , it is showing help for the oms get command.

const argv = require('yargs/yargs')(process.argv.slice(2))
    .usage('Usage: $0 <command> [options]')
    .command({
        command: "oms login",
        desc: "Login the User to OMS",
        builder: {
            username: {
                alias: 'u',
                demandOption: true

            },
            password: {
                alias: 'p',
                demandOption: true
            },
            auth_url: {
                alias: 'a',
                demandOption: true
            }
        },
        handler: (argv) => console.log(argv),
    })
    .command({
        command: "oms get",
        desc: "Get the Status",
        builder: {
            url: {
                alias: 'u',
                demandOption: true
            }
        },
        handler: (argv) => console.log(argv),
    })
    .help('h')
    .alias('h', 'help')
    .wrap(null)
    .argv;

index.js oms get

Options:
      --version  Show version number  [boolean]
