When exactly does the electric motor work?

In comfort mode, the ICE activates above 55mph i.e. at motorway speeds.

When the ICE is on, does the electric motor still actually work if just cruising?

I've read the comprehensive technical document on it, which is great, and it says you get electric assist with 1) low rev range/torque fill and 2) e-boost/kickdown.

But if you've got a full charge, going at 70mph, and the ICE is chugging along on cruise control so a steady load at medium rev range, will the front electric motor actually still contribute to a % of that 70mph, or is it entirely ICE in that situation? What is the power distribution?
