Inspecting devtools console

Hey there.

I'm doing automated tests using Javascript, Selenium and crossbrowsertesting.com

I'd like to 'inspect' the console logs of the browsers that i use in my tests.

How could i do that?

I tried what i found in the Selenium docs but it did not work:

const cdpConnection = await driver.createCDPConnection('page')
await driver.onLogEvent(cdpConnection, function(event) {
  assert.equal(event['args'][0]['value'], 'here')
})
await driver.executeScript('console.log("here")')

driver.createCDPConnection('page') <-- generates an exception.

Any pointers appreciated.

Thanks.
