I created a script in Google sheet to automate google calendar events from the sheet. The script works like a charm for my calendar but is not working on my client's calendar even after adding the correct calendar ID. My client is the actual owner of the Google sheet. I just created the script. When my client tries from his end, the script doesn't work and doesn't populate the events into the desired calendar. I'm not sure what's wrong. Kindly help.
Thanks.
