Edge options(arguments) ignored in Linux

Hello there,

I am able to start Edge on my local Win machine with the following parameters when running from Robot Framework.

${EDGE_OPTIONS}  Catenate  SEPARATOR=
    ...  use_chromium=True;add_argument("--user-data-dir=${PROFILE_DIR}");
    ...  headless=True;add_argument("--no-sandbox")
    Open Browser  about:blank  browser=${BROWSER}  options=${EDGE_OPTIONS}  remote_url=${SELENIUM_GRID_HUB_URL}

When running it on Linux Docker container with Selenium Grid, the Edge dev browser starts without the parameters such as 'headless',etc.

Here are the Edge details

Edge version

How to make it working? I have not found any related topic/issue.
