Get data in real time

when I want to try to get data in real time using the clock component, but I have an issue where the dynamic card keeps appearing with blank data, I want to get the data without having to move the screen, because when I change the data then in the application it will also change but this does not work with the dynamic card view component, maybe I forget a block?

This is firebase??

web Spreadsheet

What type of change?
Edited any cell or added new entry?

Airtable or Google sheet??

For example, if I change data in Google Sheets automatically the data contained in the application changes in real time without having to open the application again or switch to another screen, because I have tried to get realtime data using firebase and it worked but not with others. i use google sheet database
