Hey @igorcastro018ffq0, I’d encourage you to check out this setup! Would love to help you get setup here as I am a big fan of the power that Firebase provides!
I use this method in a few apps. After you get it set up, if you aren’t having success, please share you block combination that you are using.
Also, please be sure that your firebase security rules are set to allow read/write access while you are testing your app.
