Display changes in the Repeating Group

Hello!
I would really appreciate any thoughts and suggestions on the following:

In our project, we use a local database. When changes occur in the database, they are automatically reflected in the Repeating Group, which is based on this database.
We need to switch to an external API (external database). However, in doing so, we lose the ability to dynamically display changes in the Repeating Group when data in the database changes.
What options are available for us to display changes in the Repeating Group when the state changes in an external environment (database)? Do you have any examples that you could share?

Thank you in advance for your help.
