I have a fitness trainer platform, so trainers can subscribe and manage their own business through that platform. Each time a trainer subscribe, a subdomain is created and he/she receives his/her personal progressive web app.
Each trainer can then have their own clients subscribe to their personal pwa and receive personalized online coaching.
I want to have push notifications and real-time messaging between each trainer´s pwa and their clients using Firebase. So far I can send a test message from Firebase and received it (as seen in the console), but nothing is showing up on the screen yet.
