Internally, an address is just a 32-byte array.  
So just ensure that the first argument is the 32 bytes of the address (without checksum and with base32 conversion).

See [Overview - Algorand Developer Portal](https://developer.algorand.org/docs/get-details/accounts/) (where the actual 32-byte address is called “public key” in this document) and [How to convert public key back to address in js sdk - #3 by fabrice](https://forum.algorand.co/t/how-to-convert-public-key-back-to-address-in-js-sdk/3643/3)
