SSH Agent Forwarding TO my mac

I'm trying to SSH into my mac from my phone and run a script. The script copies files to a server over SSH and uses a key. I have a key on my phone that I can use to ssh into the server directly. I'd like to forward the key on my phone. Instead what happens is the 1password SSH agent window pops up on my computer (which I'm not at) and the script hangs.

From reading the following thread, I was under the impression that what I'm describing should now work.

Is there something specific I need to be doing to make this work? Is what I'm describing not possible? I have the following in my ~/.ssh/config:

Host *
IdentityAgent "~/Library/Group Containers/2BUA8C4S2C.com.1password/t/agent.sock"

I tried various things in specifying the server in my config but none seem to work (i.e. setting/unsetting IdentityFile and IdentityAgent).
