Pairing Cogeco remote to my Onn Roku TV

Hi,

Been trying to pair my Cogeco remote to my Onn roku TV with no luck. Does anyone have any tips or trick? My S.O and I have gone through the built in pairing process on the Cogeco system with no luck. Even selecting the Onn brand as the one to search for while pairing.

Any help will be greatly appreciated at this point.
