Pairing Xfinity x11 remote to ONN./Roku tv

Trying to pair Xfinity X-11 remote to a ONN./Roku tv.  The codes suggested don't work.  Only able to get the remote volumn and on/off to work.  Is there a remote on the market that I can get to work that has a keyboard on it that will work with the Xfinity app on TV.  The current ONN remote does not have  a keyboard on it( which is a total design flaw by mfg) . Stupid
