Set screensize in docker

Hello,

How can i increase the screen size of window in my docker container headless mode.
This is the command:
bash -c ‘apt-get install tree -y && rm /katalon/katalon/source/Include/drivers/chromedriver_linux64/chromedriver || true && mkdir -p /katalon/katalon/source/Include/drivers/chromedriver_linux64/ && unzip /tmp/chromedriver/chromedriver.zip chromedriver -d /katalon/katalon/source/Include/drivers/chromedriver_linux64/ && tree -L 3 /katalon/katalon/source/Include/ && xvfb-run --auto-servernum --server-num=1 /opt/katalonstudio/katalonc -retry=0 -testSuitePath=“Test Suites/Generic_Test_Cases/xxxx”-executionProfile=“xxx” -browserType=“Chrome” -apiKey=“xxx” -projectPath="/katalon/katalon/source/xxxx.prj" --config -webui.autoUpdateDrivers=true --env DISPLAY_CONFIGURATION=1024x768x24’

It seems like maximize window keyword also is not working.

Thanks
