Omnibox API: Is there a way to inline autocomplete from history?

Question

In my example I want to make extension for easy redirection for subreddits at reddit.com. This is what I have so far. However I would like to autocomplete from my history in omnibox, like those google search suggestions. For example if I type te to autocomplete tech inline and add suggestion underneath for technology and whatnot I have in my history that starts with "te". Is this even possible? If so can you point me in the right direction?

This is my very simple code so far

function navigate(url) {
  chrome.tabs.query({active: true, currentWindow: true}, function(tabs) {
  chrome.tabs.update(tabs[0].id, {url: url});
  });
}

chrome.omnibox.onInputEntered.addListener(
  function(text) {
  if(text.indexOf(' ') == -1) {
  if(text.indexOf('/r/') == 0) {
    navigate("https://www.reddit.com" + text); }
    else if(text.indexOf('r/') == 0) {
    navigate("https://www.reddit.com/" + text); }
    else 
    navigate("https://www.reddit.com/r/" + text); 
  }
  });
