Request to elaborate the readme

Hey there!
Thank you very much for all your work!
In your code you use:
https://docs.databricks.com/api/gcp/workspace/temporarytablecredentials/generatetemporarytablecredentials
Which states:
Get a short-lived credential for directly accessing the table data on cloud storage. The metastore must have external_access_enabled flag set to true (default false). The caller must have EXTERNAL_USE_SCHEMA privilege on the parent schema and this privilege can only be granted by catalog owners.

I had to dig in the code in order to understang why do I get 403.
Can you please refer to the API perquisites?

Trying to save the trouble for others.

Also, will a support for views be implemented anytime?
If not, is it possible to contribute?
I didn't see an option to open a branch in the Git UI.
