I'm trying to setup Oura with preview and pre-production testnets. Does anyone know what values to use in the config? Here's the data that I've guessed so far based on the cardano-node config files. Missing shelley_known_slot and shelley_known_time on both assuming the rest is correct. Oura config here for context: https://github.com/txpipe/oura/blob/a559934f772a2e012b514e0567cca0c34770451d/book/src/advanced/custom_network.md

cardano-cli doesn't have any way to query a block hash.

byron_epoch_length = 86400
byron_slot_length = 20000
byron_known_slot = 0
byron_known_hash = "72593f260b66f26bef4fc50b38a8f24d3d3633ad2e854eaf73039eb9402706f1"
