Thanks to @BG101 and @Rob W I found out that solution is script injection!

the only thing was that according to MDN KeyboardEvent.initKeyboardEvent() is depricated, so I replaced the code with:

var event = new Event(event, {"bubbles":true, "cancelable":true});

Also, as I wanted the trigger to run on document, I removed the element selector things. Here is what I got:

chrome.runtime.onMessage.addListener(function (request, sender, sendResponse) {
  if(request.action == "scrollToTop"){
    triggerKeyboardEventOnDocument("keydown",38);

  }
  else if(request.action == "scrollToBottom"){
    triggerKeyboardEventOnDocument("keydown",40);

  }
  else if(request.action == "enter"){
    triggerKeyboardEventOnDocument("keydown",13);
  }

  function triggerKeyboardEventOnDocument(event, keyCode){
    var script = document.createElement('script');

    script.textContent = '(' + function(event, charCode) {

        //Create Event
        var event = new Event(event, {"bubbles":true, "cancelable":true});

        // Define custom values
        // This part requires the script to be run in the page's context
        var getterCode = {get: function() {return charCode}};
        var getterChar = {get: function() {return String.fromCharCode(charCode)}};
        Object.defineProperties(event, {
          charCode: getterCode,
          which: getterCode,
          keyCode: getterCode, // Not fully correct
          key: getterChar,     // Not fully correct
          char: getterChar
        });
        document.dispatchEvent(event);
      } + ')(' + '\"' + event + '\", '+ keyCode + ')';

    (document.head||document.documentElement).appendChild(script);
    script.parentNode.removeChild(script);
  }

});
chrome.runtime.sendMessage({action : "show"});
