Broken Ignition Coil Wire

2019 Corolla Hatchback 61k Miles I started having a cylinder 3 misfire on Saturday, and the dealership is booked for 2 weeks. So I've been trying to work through it myself in the mean time.

I went to AutoZone today to swap around the ignition coils to see if the misfire would follow, but I noticed this broken wire on the 3rd cylinder . Anyone have tips on best way to fix this? Most the fixes I've seen are for replacing the broken connector but not broken wires.
