Accessing Emailed Attachments from your app

[SITECH_Mid-Cana]

Hey Guys, I am trying to make my emailed attachment pdf to be aaccessible from the link in the app. I am trying to understand the basics of linking to one specific file on my google drive for now. I can’t get it to work. The file path in the google drive is mydrive/appsheet/data/attachments/SITECH_723242305_V15.pdf
I have a column that is a FILE type. My initial value is URL to the file which looks like this.

I get 404 file not found. What am I doing wrong?

Thanks,
