I don't like to click on complicated links, so I haven't seen the sample.
You can insert emojis in PR subtitle tool or the regular graphics text. For example, in windows, Windows key + ; (semicolon) brings up emojis to insert. There appear to be many methods, but I had trouble getting some to work.
In the subtitle tool, I see the emoji with color in the Text Panel, but no color in the Program Monitor.
