questions

1. Can someone tell me how to verify that the transaction signer is the owner of the cNFT within a Solana program instruction?
2. Is it done using VerifyLeafCpiBuilder?
3. If so, how should VerifyLeafCpiBuilder be used correctly? I encountered an error when using it, as shown below:

error
