return more information about the results of contract calls

Is your feature request related to a problem? Please describe.
I'm developing a cli tool using near-api-js that executes ft_transfer. I want to get the transaction hash of ft_transfer. But now near-api-js only returns result.status.SuccessValue.

return getTransactionLastResult(rawResult);

Describe the solution you'd like
I would like to be able to provide a parameter that allows the user to control whether or not to return information about the results of all contract calls

 private async _changeMethod({ args, methodName, gas, amount, meta, callbackUrl, raw }: ChangeMethodOptions) {
        validateBNLike({ gas, amount });

        const rawResult = await this.account.functionCall({
            contractId: this.contractId,
            methodName,
            args,
            gas,
            attachedDeposit: amount,
            walletMeta: meta,
            walletCallbackUrl: callbackUrl
        });

       // control by raw parameters
       if (raw) {
           return rawResult
      }
      return getTransactionLastResult(rawResult);
 }
