Selenoid - Emulating mobile in ChromeDriver / Python

Question

I try to set experimental_option on ChromeDriver by Selenoid UI. I tried a lot of cases but neither works, usually, I see a normal browser without mobile emulation in local Selenoid UI or browser is set as unknown when I try another way and I don't have a capabilities dictionary.

My code now, which doesn't work correctly:

        capabilities = {
            "browserName": "chrome",
            "version": "80.0",
            "enableVNC": True,
            "enableVideo": video,
            'screenResolution': "1920x1080",
            "chromeOptions": {
                "mobileEmulation": {
                    "deviceName": "Nexus 5"
                }
            }
        }

        context.browser = webdriver.Remote(
            command_executor="http://selenoid:4444/wd/hub",
            desired_capabilities=capabilities)

Maybe somebody knows how to set experimental options in the chrome image in Selenoid UI?
