Creating simple On and Off switches

Hi,
I have just flashed an NSPanel with the Blueprint automation.
I want to create a simple substitution for my home heating controller as a starting point.
As such I want the physical Left button to switch the Relay one ON and then have the physical Right button switch the relay one OFF.
As such each button is not asked to toggle the relay on and then off on the next press. What I am asking is that each button becomes a single state flip-flop trigger or press and hold.

So the logic is
Left button press > Toggle relay one ON + Toggle Left button state to ON + Toggle Right button OFF
Right button press > Toggle relay one ON + Toggle Right button state to ON +Toggle Left button OFF

The left button can only switch the relay on and can never turn the relay off, and the right button can only turn the relay off can never turn the relay on.

This seems like a fairly basic functionality - but its not obvious to me how I can automate it but it has to be said that HA is new to me.
