App Blocked Message

[Manav Chadha]

I'm experiencing a problem with google ads scripts at the moment. I was implementing a script to one account and when I had to authorize the script, where data from the ads account is send to a google spreadsheet, following message appeared in a pop up:

This app is blocked

This app tried to access sensitive info in your Google Account. To keep your account safe, Google blocked this access.

There was no link to access advanced options and I don't find any information on how to authorize my script with another approach.

The script I tried to authorize works perfectly fine in other ads accounts. 

Are you please able to assist with this?

Thanks
