Best way to bring in a Zoom Audio into D Command

[postman56]

I'd appreciate any suggestions of the best way to do this:
I need to get a audio feed off my Focusrite box I'm using to connect for Zoom calls into the D-Command so the vo talent can listen to their direction. I've just currently have been using an external mic and opening the talkback when they are directing direct of the laptop.
I'm using channels 1& 2 output of Protools and C2 Main in the cue off my headphone amp, as a send into the Focusrite and down to the client.
Can I use a analog input off my 1/0's possible, but then I'd have a loop?
Any suggestions would be greatly appreciated if anyone have some experience.
