is there a way to achieve this if you don't know the list of permissions beforehand, not having to provide BulkCheckPermission api an explicit list of permissions to check?

👋 not at the moment, in that case you probably want to https://github.com/authzed/spicedb/issues/1505

thanks, and finally would you mind pointing me to an example of how you would use BulkPermissionCheck using java spicedb client?

we don't have a java example for bulk check, but perhaps you can get a feel from these other examples: https://github.com/authzed/authzed-java/blob/main/examples/v1/App.java
