verifying contract through foundry fails

[MuesliW]

example of foundry.toml

I reference this documentation (https://docs.bnbchain.org/opbnb-docs/docs/tutorials/opbnbscan-verify-hardhat-truffle) and try to verify contract through foundry:

[etherscan]
opBNB = { key = "${ETHERSCAN_API_KEY}", chain=5611, url="https://open-platform.nodereal.io/${NODEREAL_KEY}/op-bnb-testnet/contract/" }

Message

Error: 
expected value at line 1 column 1

The contract is pushed and deployed on the network however it is not verified on the opBNBscan

CLI:
forge create

Suggest you verify contract using hardhat as explained in doc
