How i can click and hold button in Robot Framework? And how to get background color of the button?

I've just started learning automation, and robot is my first framework, I'm solving some tests from letcode.in practice. But I can't solve two problems from the second test: 1) Get the background color of the button 2) Press and hold the button. I will be grateful for any help or comments.

    Click Button    id:home
    Go Back

    ${y_coord}=    Get Vertical Position    id:position
    ${x_coord}=    Get Horizontal Position    id:position
    Log    Y coordinate: ${y_coord}
    Log    X coordinate: ${x_coord}


    # ${color}=    Get Element Attribute    id:color    style.background-color
    # Log    Button color:${color}

    ${tall&fat}=    Get Element Size    id:property
    Log    Button sizes: ${tall&fat}

    Element Should Be Disabled    id:isDisabled

    # Click Button    ${hold_button}
    # Click Element   ${hold_button}    
    # Sleep    3
    

I`ve commented my last attempts, I'm a beginner, so I'm not sure if I'm good at reading documentation and searching for information on the Internet.

this code is currently working for me:
