Use Google Apps Script (or GCP) to create PDF/Google Slides of iframes that contain Looker Studio dashboards -- 2

I am seeking help to build an automation that could be manually triggered and could run on a scheduled basis that will take a snapshot of my Looker Studio dashboard with custom control filters applied then it will group the snapshots appropriately into individual files. The files will then be distributed into the appropriate stakeholders’ folders. Ideally this will all be done with a Google Workspace and/or GCP environment.

For clarity: my main challenge, and the solution I am looking for:

- Automatically create multiple PDF documents or update a single Google Slide document from an iFrame
- Using Apps Script and / or Zapier
- Hosting service: Google Drive

Restrictions:

- I am unable to use other third-party Apps / services
- Other than Apps Script, Zapier and GWS
- I cannot change the visualization tool and storage service

Solution:

- I am not looking for you to implement the solution for me
- I require simply clear and detailed instructions
- I will implement myself

Suggested payment structure for your proposal:

- 1/3 for high-level solution overview (you let me know you have a working solution)
- 1/3 for low-level solution documentation (you document your solution in a way that will allow me to implement it)
- 1/3 after I successfully implement the solution

Attached is the concept I'm trying to achieve
