how to judge whether there is a "if" in a expression

[alexanderhawl]

function executeOperation( address[] calldata assets, uint256[] calldata amounts, uint256[] calldata premiums, address, // initiator, bytes calldata params ) external returns (bool) { address pool = IAaveV2Provider(radiantV2Provider).getLendingPool(); if (msg.sender != pool) revert InvalidCaller(); bool charge;

in this code snippet, there is a if sentence about msg.sender, but how to use slither to find it? I tried use func.expressions, but it can't get the right answer.
