Change modal position

Hi,
is there a way to change the position of a modal?
I tried

New-UDFloatingActionButton -OnClick {
    New-UDStyle -Style '		
        position: fixed !important;
        top: 50px !important;
        right: 10px !important;
        ' -Content {
        Show-UDModal -Content {
            New-UDTypography -Text 'hello world'
        }
    }
}

and

New-UDFloatingActionButton -OnClick {
        New-UDElement -Tag 'div' -Content {
            Show-UDModal -Content {
                New-UDTypography -Text 'hello world'
            }
        } -Attributes @{
            style = @{
                position = 'fixed'
                top = '2px'
                right = '10px'
        }
    }
}

but no luck, its still in the center.
