How to get a Zcash t address

I would like to create a Zcash t address to use it for mining in a pool. I installed the latest version of the Arizen lite wallet for Windows. It lets me to generate new addresses. But all of them start with “z” even if I chose “T (Transparent)” option. Though the pools need an address starting with “t” otherwise I obtain the “Worker not authorized” error. Could you please tell me how to get a Zcash t address?

Sorry for the beginner’s question.

If it disallows t generation and that is what you require then you should use another wallet
