Does spicedb have an equivalent api to Permify Bundles? It's essentially a store of templates for creating multiple tuples/caveats, and then an api that allows you to call do that "bundled operation" as one API call. https://docs.permify.co/docs/api-overview/bundle/write-bundle/ . They also have an interesting API where you can look up which permissions a user has, which seems handy. I think it could be handled by the expandPermissions api? https://docs.permify.co/docs/api-overview/permission/subject-permission/
