Python/Ionic/MySQL Notifications

I have a code in Python that inserts data into a table in MySQL. What I want to do and I do not know how to do it is to be able to receive the data that is inserted in my application in Ionic. By this I mean to be able to receive only that data that is inserted (not the whole table) to be able to notify in the application, each time a row is inserted in the table.

I tried to do it with observables but I did not understand much about that and it did not work either. The other thing that occurs to me is to use web sockets but I do not know if it will serve me correctly.

If someone can guide me or help, I would greatly appreciate it.
