For weeks now i have been trying to get this to work, with no success so far. I want to create an application with which i can create a new Event on my Google Business (for Google Search, Google Maps, etc.). Afaik, for this Google has the Google Business Profile API. In this Documentation, there also even exists the Page “Create Posts on Google”. However, none of their documentation makes my dumbass here understand, what i need to do to be able to use that API in my code.
I have tried several approaches:
Google has a library for google my business – place actions, for Java. I remember that I tried to integrate it into my Code, but with no success, since i cant find any proper documentation or anything on it.
Also, i tried just using plain old HTTP requests, but now I am stuck here as well.
So far, i have managed to get an access token through their Google Sign In library, but using that to request the creation of a new Event only results in the 401 (Unauthorized) Error.
This is my current code:

Any further help, hints or ideas would be hugely appreciated – thank you!
Edit: I have a suspicion that the requested scope is not correct, hence why it returns RESULT_CANCELED when trying to authenticate. When opening the scope URL, i am only greeted with an error and a not very helpful link.
