      await console.log('hello');

      const driver = await wdio.remote(config);

      // const a = driver.byText('Update Now');
      // await driver.elementClick(a);

      // const b = a.getElementText();

      // .waitForPaymentSuccess())
      // .getCounter()
      // expect(value).to.be.eq('1')
    });
});

I attempted various approaches, including adding prefixes to the capabilities and removing them, but none of these assumptions yielded the desired results.
