+Usage example of `encode_data` task. Here we want to call ProofManagerV1 function called setReq, and this function can be called only through `forwardCall` in HubController and encoding arguments for this function can be done by using this task:
+```sh
+npx hardhat encode_data --contract-name ProofManagerV1 --function-name setReq 1 true
+```
+Alternatively, encoded data can be produced from Remix by copying prepared calldata from ProofManagerV1 setReq call.
