Am trying to do this as well.
Given I’m doing this as a non-programmer, I’m struggling to get the connections through to Firebase.
My Real-Time database is collecting data from my mobile apps. So I can see the data logging in to Firebase directly
I have also created a service account for view-only on that real-time database.
Would like to use this plugin to use a view-only service account so I can display that data, but the examples arent clear enough for an idiot like me to follow.
Am happy enough to go “if logged in to wordpress then use this service account to get data”….
My end state is going to be to create member logins in my website where everyone can see their OWN Firebase data.
