Does this plugin support Australia Post connections>

I have Australia Post linked to my Shippo account and only have Sendle active out of Shippo’s accounts (as these are the only two services I use).

When I set this plugin up, I’m only getting live rates from Sendle and not Australia Post, is this because the plugin doesn’t support carriers that are connected via our account? Or is there any way to get this plugin to show the live rates for Australia Post?
