How to resolve GSuiteApplicationScope duplicate sheets

When I run it, it creates a sheet with today’s date, but if I run it again after a few seconds, I get a warning that the sheet already exists.
To solve this, I want to use an if statement so that if there is a duplicate sheet, it is skipped.
What should I do? Any help would be appreciated.



Why can’t we add time?

I mean instead of creating the sheet with current date. Add time also to that sheet

Now.ToString("dd-MM-yy hh:mm:ss")

This will keep on create a new sheet
