Sonoff Mini R4 garage opener wiring?

Hello,

I usually use the mini R4 to manage lights, I know it can be used for lot of other things.
I would like to use it with my garage opener but I can’t do it unfortunately, I want to confirm if it’s already possible.
Here is specs for my garage opener control unit (in french) 106605.pdf.
I want to add the mini r4 as secondary smart control and keep unit normal functionality (with remote control and “p.Alt” switch.

Thank you for your help !
