Adding TradeMe to MS Authenticator App

I've bought a new G5 smartphone and installed MS Authenticator on it.
I use  multi-factor authentication in TradeMe I need to add TradeMe to the list inside Authenticator. In order to do that Authenticator displays the following message:

"Your account provider will display a QR code" which it wants to scan.

My question is where do I find the QR Code for TradeMe?

Thanks for your help.
