How to hook up "LANDR Mastering Plugin"

[Rothgarr]

I was thinking of purchasing the LANDR Mastering Plugin:
https://www.landr.com/plugins/mastering-plugin

There is no demo version.

I have a bazillion VST2/3 instruments and effects, and I know exactly where to drag those to use them (they automatically connect the wires, etc). But I'm not sure where I'd drag this to use it. In the video at 0:22 (

they say to put it on the “Master track” and then select “LANDR Mastering” > “Stereo”. Even though I've used Reason since 2002, I have no idea what they mean by Master Track.

So, where do you think I would drag this to be able to use it? I'd hate to spend a couple hundred bucks on this and not know where to place it in the rack, etc.

Thanks!

Put it between the main mixer outputs and the hardware interface.
