Generate an access token organisation wide to access figma file content from different teams in the organisation

I am trying to create a script that would use figma apis to extract data from figma files. This script would run as a scheduled cron job and would be dealing with figma files from multiple teams. 
The basic approach of creating a PAT (Personal access token) seems very difficult to manage and scale as we have to get access to all figma files for the particular user.
Is there a better way to achieve this ? Can an org wide token be created to achieve this ?
What are other ways of performing such actions in production environments
