OpenZeppelin Sentinel Function Condition Variable Not Reocgnized

I am having issues creating a new Sentinel condition due to a function parameter not being recognized when trying to create Sentinel conditions to filter transactions.

I am trying to use Sentinel.

While creating a new sentinel to monitor the following contract on mainnet:
0xfa4d5258804d7723eb6a934c11b1bd423bc31623
I tried to create a new condition to filter on the contract's borrow() function. The problem I'm having though, is that when trying to create a filter on one of the function arguments, the variable I am trying to filter (_lenderSignature) is not recognized due to "Undefined symbol _lendersignature".

The filter I tried to test with was:
_lenderSignature[2] == "0x123"
