Safe App Transactions: how to configure the "operation" enum

[kassandraoftroy]

We're working on a feature at beta.arrakis.finance which batches a few operations together for gnosis safe users. In order to do so we can create the payload to the MultiSendCallOnly contract but the operation field of the Safe transaction needs to be set to DelegateCall (1) not the default Call (0). So far we can't figure out how to manually set/configure the safe transaction so that operation is set to 1 with wagmi. Is there a way this could be exposed as an optional argument in usePrepareContractWrite for gnosis safe type wallets ? Are we missing something. SO far we've tried all kinds of things but have had no success being able to queue up a safe transaction that uses the delegatecall operation type.
