How to define webDriverCapabilities ?

[CondormanFr]

Hi,
I want to define webDriverCapabilities for Chrome webdriver.
For example : --headless,--disable-gpu
How to set that in the saga configuration ?

It works for jasmine with this kind of setup :

<webDriverCapabilities>
  <capability>
    <name>browserName</name>
    <value>chrome</value>
  </capability>
  <capability>
    <name>chromeOptions</name>
    <value implementation="org.openqa.selenium.chrome.ChromeOptions" >
      <args>
        <value>--headless</value>
        <value>--disable-gpu</value>
        <value>--window-size=1640,480</value>
        <value>--disable-plugins</value>
      </args>
    </value>

  </capability>
</webDriverCapabilities>

Thanks for help
