In SpiceDB, this is known as the LookupResources [1] API, which returns all resources (of a particular type) that a particular subject (user in this case) has a particular permission on.

We have a guide on doing ACL-aware filtering and listing [2] with this API and describing other approaches for larger Enterprise scales

Disclaimer: I'm the co-founder and CTO of AuthZed, we develop SpiceDB, and I wrote our most recent implementation of LookupResources
