The 'smart' openers have a continuous voltage across the 'smart' button controller. The controller button has a clock and provides other functions. Creating a short across this circuit, with a parallel relay, reboots the 'smart' controller.
Last time I had a GDO replaced in my home, I opted for a 'dumb', old-fashioned model, to ease integration.
If you can remove the fancy pushbutton controller (which displays the time) and replace it with a simple pushbutton, I think your relays should work. Not sure if that is an option for you.
We run wires to the openers AND the buttons now. For smart openers we solder to the button contacts not the opener. Works every time The existing wiring from the button to the opener has to remain as is without interruptions.
