Hi Team, I am running the flashbots block builder on holesky using the flashbots boost Relay. I know, I have to change genesis_fork_version, genesis_validators_root, bellatrix_fork_version, remote_relay_endpoint, and secondary_remote_relay_endpoints to run the builder on the mainnet. If I use the flashbots boost relay as the remote relay endpoint would it accept blocks from my builder? Should new builder need any pre-registration or meet any other requirement to send blocks to the Flashbots mainnet Relay? Thanks.
