.net maui notifications without firebase?

[sadrirammal]

Hi there excuse the dumb / beginner question but I would like to implement notifications for my Maui production app without using firebase. I was hoping there is a way to implement a polling approach to fetching notifications (Call my API endpoint every few hours). I don't need push since my notifications aren't time-sensitive.

What would be a lot more important for me is not to have platform-specific code(target platform is iOS and Android) to reduce maintenance. Is there even a way to do this?
