danish characters custom key combinations

So the problem is I have a standard QWERTY keyboard, but I want to be able to type specific danish characters. I have tried to follow the example of this post Using ctrl as modifier to produce swedish letters å, ä & ö on us keyboard while typing. Which I cannot make workfor some reason.

My current active keyboard layout is English US.

I have insterted the following below.

/usr/share/X11/xkb/symbols

partial alphanumeric_keys
xkb_symbols "danish" {

    include "us(basic)"
    name[Group1]= "English (US, with åæø)";

    key <AD11> { [ bracketleft,  braceleft,  aring,       Aring      ] };
    key <AC10> { [ semicolon,    colon,      odiaeresis,  Odiaeresis ] };
    key <AC11> { [ apostrophe,   quotedbl,   adiaeresis,  Adiaeresis ] };

    include "level3(ralt_switch)"
};

/usr/share/X11/xkb/rules/evdev.xml I have added the variant as the first in the list under English (US) like below

  <layoutList>
    <layout>
      <configItem>
        <name>us</name>
        <!-- Keyboard indicator for English layouts -->
        <shortDescription>en</shortDescription>
        <description>English (US)</description>
        <languageList>
          <iso639Id>eng</iso639Id>
        </languageList>
      </configItem>
      <variantList>
        <!-- Added danish mappings -->
        <variant>
                <configItem>
                        <name>danish</name>
                        <description>English (US, with åæø)</description>
                </configItem>
        </variant>

and restarting the keyboard service with systemctl restart keyboard-setup.

I do not have any combinations the expected mappings does not work, I have tested that the Meta R/Alt R and the key presses is detected as expected.

My current selected language is displayed as English (United Sates) (not English (US) as the mapping might suggest it should?)

I cannot find the other variants listed below under input sources like

          <configItem>
            <name>colemak</name>
            <description>English (Colemak)</description>
          </configItem>
        </variant>
        <variant>
          <configItem>
            <name>dvorak</name>
            <description>English (Dvorak)</description>
          </configItem>
        </variant>
``` etc.
