Notifications on onesignal?

Hi, I'm integrating notifications for my native apps made with Bravo.
I looked for some video tutorials on the topic, and I want to be sure that I'm able to implement this without the need of writing some scripts with real code.

The notifications will need to fire only when called by some Xano endpoints, so it's not something complicated, I wish I could find some examples or videos or documentation but I couldn't

Do you have some documentation or does anyone have experience with Onesignal in Xano?
