Ok. I’m almost a little embarrassed to say this…I have not figured out how to zap. Please help!

I have an iPhone, so I have Damus. I have getalby linked. I can receive zaps, I just haven’t figured out how to zap. I’ve messed with it a bit. I’m usually super busy and haven’t set aside the time. Can someone help? I’m not trying to be greedy with the 20 cents worth of sats I’ve received. Just need to figure out how to send it back out. I heard there was an issue with Damus and zapping. I don’t even see button to be able to zap.
