Gemini AI for Apps Script (GCS links access)

I’m trying to create a google sheet that serves as a GUI where users can select some variables using drop-downs, then a script populates a square with the links on the specified files from the GCS.

The key issue right now is that i couldn’t find the appropriate model/configuration that it would actually access the files from those urls in the square “links”.
When i provide urls like “https://cloud.storageapis.com/…” models usually explicitly say that they don’t have an access to external links, therefore they provide general answers.
When i provide urls like “https://storage.cloud.google.com/…” models try to dilute me and say that they accessed the file and downloaded the information. But when i ask specified question regarding the document the answers are completely out of touch.
When i provide files pathways like gs://file_bucket/file_name they again try to deceive me.

What is the solution to actually make models access the files (if it’s possible)?
