2 doorbells, 1 intercom, 1 gate

I need un advice. I live in a house and would like to have my front gates (to the garden) opened with Ring. I already ordered doorbells and Intercom from Ring for that but I have a specific case. I want to have two doorbells (one for my parents that live downstairs and one for me on the upper floor). We want to have 2 doorbells so that people that visit me don’t bother them. To be pricise I want to have 2 doorbells that are independant (notify seperate screens,phones…) but are both able to open the same garden gates.So what plan will unable me to do that? Thanks in advance 🤗
