Update Google Calendar by checking a Google Sheet at Specific Times

Describe the problem/error/question: I’ve been trying to create a workflow that works as follows: at specific hours, the workflow activates and reads both a Google Sheet document + Google Calendar. With that information, it compares both and the event gets updated if there are any changes in the Google Sheet. If there are no changes, then the workflow stops. I had an idea and asked Claude for some help, but it ended up confusing me more with the codes. Am I on the right path? I would appreciate a recommendation as I am fairly new to N8N.

What is the error message (if any)?

Please share your workflow:
