i am just visiting here. not a part of the development team. hence, i can only tell you how i did this. i store users internally, in my database, however i store them. i use SpiceDB for permissions. the identifiers for SpiceDB objects and subjects are my records ids [primary keys]. i populate SpiceDB using the equivalent of:

zed relationship create organization:1 owner user:2
zed relationship create event:1 organization organization:1

Only, except for the records that I want seeded [dummy test data], instead of

zed

, which is CLI tool, I use the SpiceDB API.
