I'm using Dataplex to grant users permissions to underlying BigQuery tables.
This is done using Dataplex "data roles", which grant some (not very clearly specified?) permissions on the BigQuery tables. For example, roles/dataplex.dataWriter
gives some vague "write" permissions to users.
Is it possible to customise which permissions Dataplex will give to a user who is assigned this role, or will I just have to manage the permissions outside of Dataplex?
