Hi folks, I am very new to IAM and permission management in general. I have been asked to make use of SpiceDB for a project. With the limited knowledge I have, I was able to create some schemas and play around with permissions on the authzed playground. But now I'm trying to use the Java Client (SDK) for achieving the same. Apart from the one example given in the documentation, where can I find good docs for accessing, manipulating and checking permission via the Java SDK?
