Passing capabilities by serenity.conf file

[molobry]

Hello,
I have problem to pass my token over serenity.conf file.
Here is my code in serenity.conf file:
webdriver {
driver = "remote"
remote.url= "https://seleniumbox.test.com/wd/hub"
base.url = "https://test.com/"
autodownload = false
capabilities{
"e34:token":"12345678-0fde-45"
}
}
I am getting error: Response code 500. Message: A test token needs to be provided via the e34:token capability

But I'm passing token. I think problem is in key
`Driver info: org.openqa.selenium.remote.RemoteWebDriver
Command: [null, newSession {capabilities=[Capabilities {"e34:token": 12345678-0fde-45, browserName: chrome, goog:chromeOptions: {args: [], extensions: []}}], desiredCapabilities=Capabi
lities {"e34:token": 12345678-0fde-45, browserName: chrome, goog:chromeOptions: {args: [], extensions: []}}}]
Capabilities {}

In log key is "e34:token" why I would expect it e34:token
`
I tried multiple combination with quotes without but no success. Do you know how I can workaround this problem ?
I saw similar issue which was fixed for serenity.properties #1479

Thanks a lot.
BR,
Michal

I found workaround using BeforeAWebdriverScenario. I created new class. Then in serenity.conf I had to add serenity.extension.packages

But main issue is not resolved. I think it's bug in implementation of reading capabilities from serenity.conf file.
