@openhab/core-maintainers Where can I find information on how the /rest/auth endpoint works to generate an API token?

The code is here: https://github.com/openhab/openhab-core/blob/main/bundles/org.openhab.core.io.rest.auth/src/main/java/org/openhab/core/io/rest/auth/internal/TokenResource.java and I believe that is the best documentation that is available.
