add example of permitting arbitrary function on contract already defined by defi-kit

[SecurityIsHard69420666]

ChatGPT helped me figure out how to do this.... but I couldn't figure out how to put conditions on the args. I tried:

{
  targetAddress: "0x87870Bca3F3fD6335C3F4ce8392D69350B4fA4E2",
  signature: "repayWithATokens(address,uint256,uint256)",
  condition: c.eq("0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2"),
},

but with no luck. i don't necessarily need conditions on repayWithATokens, but I'm still curious for future reference :-P
