Copy a Looker Studio dashboard (405 error)

I want to create a simple automation that copies a dashboard created in Looker Studio and changes its name.

  1. I registered an account on Google Cloud, created an application, and set the redirect URIs (similar to the instructions here: https://www.make.com/en/help/tutorials/calling-google-apis-via-the--http-make-a-oauth-2-0-request--module).

Scropes:
Looker Studio API - /auth/datastudio.readonly - Reading resources of Looker Studio|
Looker Studio API - /auth/datastudio - Reading, editing, and deleting resources of Looker Studio|

  1. I created a Looker Studio “Make an API call” module, with a connection to my app.

  2. Based on the Google documentation
    (Looker API Interactive Reference), I wanted to create a simple query that copies a report with a given ID.

I am receiving a 405 error message, which according to Google’s documentation means:

“A 405 Method Not Allowed error indicates that the server knows the request method, but the target resource doesn’t support this method.”

For other types of queries, I am getting the same error. What did I do wrong?
