I want to be able to see pridicted incoming heals from my healers but nothing I have tried works. I have confirmed that my healer and I both have healcomm-4.0

I am using ElvUI and he is as well with healbot.

When I heal myself I can see incoming heals but not when he goes to heal me?

Is there something I am doing wrong or that I can add or change to make what I want happen?
